Gas tank arrived well packed and no damage to tank or packaging. Gas tank it self was well made good welds .will be buying more stuff from jpcycles .


Perfect fit for my 2015 Harley 48 Sportster. Good welds and overall apperance. Original 48 saddle fits with no problem. The only modification needed is to shorten the rubber return/vent line on the bike.


Tank arrived quickly. Packing was in good shape and tank was packed well as to not shift. Tank had minor build defects took very little work to clean up for paint and sealing. Upon finally installing on my 2013 HD XL1200V went from 80-90 miles with factory tank to 130-135 before low fuel light came on and then when I filled at about 160 miles still had about a gallon in reserve. By far a great investment if you ride a lot and longer trips.


High quality


good fit


Perfect fit for Harley72 Sportster. Fast shipping, no issues.


I just loved it ! fitted like a glove!


perfect condition


After reading the reviews, chances are high receiving a tank with some kind of issue. I took a chance and ended disappointed. The tank came with a dent on the right side. More body work is not in the cards for me. Going to call JP customer service tomorrow and see if they can straighten this out.


Shipping very fast,i live in france.8 days to arrive.the tank was well just a little rust inside but nothing bad!!! Just negative point to france ,i paid 90 usd of customs dury i was very happy pffff


I ordered a tank, and it came with a big dent in it. I called JP, and the rep told me to send it back in, and they would send me a new one. I left a stinky review. Within minutes, someone responded to my review with an apology, and then I got a call from a care rep from JP. They knocked 25% off the tank and sent me a new one immediately. I received it, and it's perfect. Wonderful service, J&P! I'll be a customer for life. I'll try to delete my stinky review. :) Great job!


Love the extra mileage I get from this tank. Fit my 2010 XL1200X 48 with no problems.


Cheapest tank I've found. It is solid metal, no fiberglass


Tank Rocks! Little grinding & fill to be performed. Can't wait to get those extra miles on the highway..


arrived in good condition with no dents or dings like mentioned in some previous reviews, seam welds very rough and needed lots of grinding to smooth out, haven't pressure tested it yet


Took a bit of work to get paint on the tank, the raw finish is pretty average. There was a lot of rust through the inside of the tank so ensure you do a tank clean and seal. I didn't and it cost me a fuel pump from the build up of muck.. fitment was great, if your painting the tank your self then this is a


Fit my HD 48 (2012) %100


perfect fit


Tank fit perfectly on the Sporster 48, 2010. The EFI fuel pump slipped in with no problems and the original gas cap fit right in with no modifications. The outside of the tank was nicely polished metal, the inside had a little rust. The welds were very raw and needed grinding in order to fix the pitting and jagged edges. Additionally, the tank arrived with a dent on the left side, needed to take out the dent before painting. Shipping was fast.

Not a perfect fit and it will not fit with the stock 2011 Iron 883 seat...
