Customer Reviews

 topcop Posted:

Very comfortable, good look and quality

 elrod22 Posted:

The handle grips I purchased are very comfortable and the Throttle Boss makes a long ride even more comforable! Thanks

 paloiowa Posted:

Very easy to install and very comfortable.

 jharback Posted:

These really helped with the vibration on my Sportster.

 gene992 Posted:

More expensive than Cramp Busters but looks many times better and adds looks to the bike. I have a set on each of my 4 bikes (3 Harley's and a Gold Wing). Can't imagine riding without the grips. Helps relax both hands not just the one with the wrist extension that eases pressure on your throttle hand. Works great even when you have Cruise Control and doesn't interferre with throttle operation.

 tankman Posted:

While I have only put on about 250 miles since I changed out my grips to the Kuryakyn ISO grips with the Throttle Boss I have been very pleased. Prior to the change I had the sponge type soft grips which caused me to have hand cramps after about an hour. I could not feel that I had control over the bike and no feel for the road. I did not want to go back the the factory style as you can feel all of the road in that type. The Kuryakyn grips offer me the best of both worlds, they dampen the vibration of the road and my old 81 Ironhead, but let me feel that I have control and a good grip without over gripping the controls. The product was easy to install and are very confortable. Try them you will like the feel.

 jbarbieri Posted:

Not as big as some others which is good. You can throttle without it getting in your way if you desire.

 gbkemp Posted:

Grips are nice. Package looked like it had been around a while and the glue was hard so I ended up having to go out and buy some.

 aldon Posted:

Love the grips but the instructions could be better for a first timer like me.

 slodoen Posted:

These grips have worked out great, they are very comfortable and easily adjustable. The padding and slightly larger size than stock grips has relieved my hand cramping on long rides.

 gwturbo Posted:

Fantastic grips, SOOOOOO nice. the throttle boss feature makes these grips. The daily commute is much easier on the wrist. Very easy to install as well

 84harley84honda Posted:

Excellant- very comfortable on the long rides. Greatly reduces arm and wrist fatigue. I highly recommend these grips!

 langvardt59 Posted:

With my stock grips I had trouble with my hands going numb. Since I put the ISO grips on I don't have nearly as much problem. I would recommend these grips to everyone.

 tonylockard1968 Posted:

Great grips!no More tired hands and they look great too.

 67v35er Posted:

Excellent product in appearance and workmanship. Easy install on both sides and includes the adhesive for the left grip. Wasn't sure about the need for a throttle boss paddle but after several rides now, wouldn't ride without it.

 Mcyclewriter Posted:

Easy to install, look great, absorb vibration and priced below the bike mfr's OEM product.

 GSH Posted:

Waiting on the new chubbies to install these but look and feel great. Have a pair on my Softail, really nice Posted:

 bearcatt13 Posted:

Perfect fit and easy to follow instructions

 GEdenf1219 Posted:

very nice grips. My hands don't hurt on long trips anymore & the throttle boss is also nice for long highway trips. I highly recomend these grips if you want to replace your old grips.

 dspas57 Posted:

Incredibly comfortable grips, work great even when wet.

 jwesson48 Posted:

Love the grips and the service at J&P Cycles was great.

 rmgipson Posted:

Great feel, great look. I am 100 percent glad I purchased them. So easy to install. Just add a ton of character to the bike

This product was an excellent replacement product. They were easy to install and look and function properly. I also appreciated that the inner grip was included on the throttle grip!

 fotomanlp Posted:

Grips feel good and look great on bike. Fairly easy to install.

 ruger44mag30 Posted:

 silverjay1 Posted:

really good grips! ... this is my first use of a throttle boss - it does work to keep your hand from cramping or hurting!

 Dougvida Posted:

Great product

 jearickson Posted:

Love these hand grips and they came with the throttle boss. I would not buy anything different in the future

 talbany1 Posted:

These new grips are so comfortable. Also, they look fantastic!

 Jrstone Posted:

Great looks but the throttle grip feels loose, I did have the grips professionally installed; however, it may be more about getting accustomed to the new feel.

 rooskie03 Posted:

Have had these on my bike for a year and love them. Get the throttle boss it saves a lot of trouble on long rides. All the people I ride with have the same grips and they love them.

 softwareDev Posted:

can't get much easier than these... look nice and easy mount

 mikemcclelland Posted:

love these grips--one downfall..your hands will get dirty from the rubber grips.

 Bagger Bob Canada Posted:

A simple way to add some bling to your bike while improving comfort at the same time.

 mcfhome1 Posted:

Fit awesome easy to install comfortable

 bobnbec94 Posted:

Love them! Makes it a lot more enjoyable to ride.

 chad&melonie Posted:

The grips are awesome i saw them on a friends bike and they looked great my bike had stock grips on it. After i put the ISO grips on they really set off my bike and they function great. I would highly recommend these to any one look and function great for a awesome price.....

 piggy56 Posted:

love them... that's all I can say

 chipmaker29 Posted:

Very nice product! They are very well made and look great too. I recommend using Loctite Glue when attaching lor another quality brand glue. The glue that comes with them didnt hold well and the grip worked free within few days of riding. Very nice grips, though!

 DaveBencze Posted:

Easy on, good fit, look great! Even better riding, no hand vibration, easy grip

 lauradrietz Posted:

These are awesomely comfortable and look great. The Boss is totally worth it.

 Roylove Posted:

Very nice and easy to put on. Very comfortable and look great with matching foot pegs. Pricy, but worth it.

 charliejp Posted:

These help complete the look along with the Stiletto end caps and the Stiletto pegs on my 2012 SFX Blackline

 GaryAJUSA Posted:

Well-made. When installing, get your clutch side grip (with the adhesive) on quickly as the glue sets-up fast.

 luttrell2011 Posted:

Really nice feel.

 DonStriker Posted:

No more numb hands! Buy extra glue too.

 onecent Posted:


 derekkanngiesser Posted:

top quality

 wildbill70 Posted:

Great grips. The throtle has some play sideways. I was able to look at someones bike who also had them installed and it was the same. So I'm pretty sure that the Boss function needs that play. They are great to ride and look so to.

 Mark dunlap Posted:

Love them the boss is great on the long rides

 ralphevert Posted:

These grips change the ride very dramatically. They dampen vibration and help with hand fatigue. You swear the whole bike feels different, suspension an handling become a breeze. Posted:

IMHO, the best grips that can be had.

 Brooks44 Posted:

Great product. Had the Transformer grips on my last bike, but I think I like these even better.

 Brooks44 Posted:

Great product. Had the Transformer grips on my last bike, but I think I like these even better.

 Lesliejohn Posted:

This is my 2nd set of ISO grips w/throttle boss. I love the feel of them. They take out a lot of the vibration, and the throttle boss is awesome for long rides.

 gagecutter Posted:

love them

 Anuzumak Posted:


 Golfer002 Posted:

What a difference it made on my 2011 Heritage, no more fingers going numb on long trips.

These are probably one of the most popular and comfortable/functional grips.

Good for a day trip or overnight bag Posted:

 AUMABill1 Posted:

Very comfortable for the long haul.

 adkyle97 Posted:

Looks great. Easy install with a little common sense. Looks as good as the picture. Posted:

so comfortable and the throttle boss is worth the extra on them longer rides. Dont skimp on your grips. Spend the money and get the good name brand ones like these. You wont regret it.

 Gabe80 Posted:

Great Product and Great Delivery!

 retmpo Posted:

Great Deal. W/ Free Shipping. Easy Install and they are just wonderful grips. Would order thru J& P cycles for all my needs.

Very nice, perfect fit !! Home run with these. !!

 Bigbadwolf67 Posted:

Great looking and feeling grips. Easy installation and a quick delivery from J&P. Two thumbs up.

 Pat915 Posted:

These grips make riding much more comfortable than the stock grips that came with the bike. They compliment the appearance of my 05 Springer Classic very well.

These are beautiful and fit great.

Kuryaken product as always, great stuff.

 Halfnut Posted:

Very comfortable and easy to install

Very good grips-they came with good instructions and were easy to install.I really like the throttle boss. Will recommend to others

 sgilmore99 Posted:

Nice grips! Exactly what I wanted.

 birdmandave Posted:

Looked at other grips, and none felt as comfortable as the ISO. Had them on the last two bikes. Now know why they are so popular.

 KC the Seabee Posted:

havent had time to install yet, but have these on my other two bikes because they are soft on long treks, but hard enough for everyday ridin..

 JHiemenz Posted:

Nice replacement grips. Throttle boss takes a bit of getting used to.

 OlderHippy Posted:

Fit and finish are great. A real nice addition to my FXSTS.

 jed flint Posted:

these grips fit as good or better than stock.

 BartFore Posted:

Went on easy and look great. A great value.

 robert.evans Posted:

This is the second pair I have purchased for different Harley motorcycles because they are great at reducing vibration through the handlebars.

 fitforlife0032 Posted:

These grips were really easy to install and added a great finishing touch to my Sportster. They match the pegs and shift peg. Another great product offered by JP Cycles!

 Thunde~Struck Posted:

Had them on my FLH. Now on my FXST. Great looks and quality. Throttle boss is a plus. Match up your chosen style with a set of pegs for a great and functional look. How often do you find something that fills both bills. Posted:

Easy fit. Look and feel great!

 Super glide 2013 Posted:

Good looking grips made my bike look better and easy to install.

 tomacree Posted:

The grips don't relieve hand fatigue nearly as much as I expected. Other than that, they are comfortable, they look good and installation was easy.

 jpotasnak Posted:

The best need I say more?

 MrChicken2U Posted:

Have them on all my bikes, excellent made, pricy, but you get what you pay for!

 SGT_Rock Posted:

Very comfortable grips. They have saved me from the cramps I was having with the old grips.

 edobernig Posted:

 daniel.mcintyre1977 Posted:

wife loves these on her sportster.

 rcolumb Posted:

Great looking grips. Love the extension of the heel of my throttle hand.

 mr05tundra Posted:

Stylish Grips, the left side grip (one that gets glued on) is now rotating after one season of use. They are very comfortable even at highway speeds, vibration barely noticeable.

 smcewen Posted:

Looks great on my 03 Sportster. Help to reduce vibration

 Cmd5252 Posted:

Canceled my order customer service is very poor

 gutshot_again Posted:

Should have gotten these years ago. The hand/arm tingle is much less.

 rowgerr Posted:

great grips good around town and on long rides

 Herkyamm Posted:

Good set of grips, don't hesitate to purchase them if your hands go numb, especially in the carpel tunnel area, since I put them on my hands/wrists don't go numb.

 cpfleegor17856 Posted:

Look & feel good on the bike

 rooster2k9 Posted:

Awesome grips.

 gtquigley Posted:

They look awesome ! And work and look great!

 Blacksheepbob Posted:

They look great and feel awesome going down the road. My set has the throttle boss, and that is a nice option to have on longer rides. The boss is adjustable simply by loosing the 4 screws on the end cap, they you rotate it in the desired position. Don't forget add loctite on the screws so the screws don't vibrate out!

 dmccrea Posted:

Easy installation, good fit and comfortable on longer rides.

 bradford714 Posted:

Great look. Feels awesome on the hands when riding.

 dschneckloth Posted:

Perfect fit!!! Awesome always! I will always recommend J&P to anyone who lives the bike life!

 cmelton21 Posted:

Looks good on bike. Easy to install. I would recommend these grips to anyone.

 isleta521 Posted:

Easy to install after watching the video. The bike I installed it on is exact same as the video (FLS Slim). The only problem I had thinking I could do a short cut, I thought I could just slip the existing grip off since I had some difficulty taking out the farrels off the accelerator cables. But started to add stress to the electronic wiring so I stopped trying to pull it off - it is tempting as I only needed to pull the grip off by a half inch more but don't do it. Anyway, all went together well and it surely makes a big difference in looks. Also very comfortable and I really like using the throttle assist. Great product and nice upgrade for my slim.

 mpisula Posted:

Replaces stock grips easily. Throttle boss works great for long trips, but can be a bit touchy in stop & go traffic.

 Ronzo7575 Posted:

Great grips, no more numb fingers, Palm does all the work.

 cybergent Posted:

We love these. They make the bike look so much better.


The iso grips 500-153 fit perfectly on my new "beach bars". They look great and were easy to install. Even the instructions were easy to understand. The throttle boss works quite well on short rides and not so short rides.

 jayb1367 Posted:

These grips are by far the best and most comfortable grips I have ever owned. Thank you JP cycles. Posted:

Looks great on the bike

 fperch Posted:

these grips are great I have had them on 3 of my Harleys and i love them they are great for the long rides

 bucky000 Posted:

Great grips, very easy to install. 10 minute job and that includes time to read the instructions. Love the throttle boss.

 PeteNichols Posted:

Like the grips. Comfortable and easily installed.

 harley_rly Posted:

These are some very comfortable grips, my father actually has the same ones on his bike. One problem I ran into, however, is that they are for electric throttles, whereas my bike has a mechanical throttle.

 mte12373 Posted:


 2hogs Posted:

Great good quality product, easy install, .

 rmeldrum Posted:

Very easy installation and also looks great on the bike

 bcran03 Posted:

Very comfortable compared to the stock grips. Got the throttle boss as well which allows the throttle hand to relax a little making those longer rides much more enjoyable. Quality product for a great price!

 clinkr Posted:

excellent grips, and quick shipping

 rklapper Posted:

Has a nice feel and is quite comfortable as your palm fits on the extended palm rest to crank on the power during acceleration. Will be installing a pair on my friend's bike soon.

 Diamon47 Posted:

First of all these ISO grips are awesome, comfortable and easy to install in no time at all. I also bought a throttle boss which is great on long rides. I used Customer Service to find the correct throttle boss to match the grips. The customer service representitive was friendly and knew her job. My items arrived fast and the packaging was great and I am also happy with the price I paid. I will be a repeat customer...Thanks.

 Mark dunlap Posted:

I love these grips. This is the second bike I put them on.

 bcapollo Posted:

Love the look and feel of the grips but need to find a better cement for clutch side. Because of the square hollow cells there isn't enough flat surface area for the adhesive to bond to.

 emersonpalacio Posted:

very good product and the

 Nevtat Posted:

Have used these grips on 3 Harleys and they work great and look good too.

 kenmaltman Posted:

Great grips, have them on both of my bikes and the GF's bike

 Ers0429 Posted:

The best grips out there

 TheCoffee Posted:

They look and feel great, larger diameter then the stock grips so fit my large hands better. Let grip fits the bars fine but the right (throttle) grip is loose in the switch housing causing a slight wobble. Don't like that at all.

 jdipento Posted:

Great quality. Look forward to relief for hands.

 jamielarson10 Posted:

Love the grips. Night and Day difference. Item was shipped incomplete (no glue). JP shipped the glue right out.

 1Bushmaster Posted:

This is the 3rd pair I have had. They're great.

Great product. I used these grips along with the helmet locks. Looks and works great.
