Best thing I have done for my bike


I've upgraded the suspension on Harleys before but this time I decided go with a better solution. Having multiple bikes in my 35 years of riding I had a pretty good points of reference which include sport bikes. This suspension set up is on par with sport bikes that I have ridden. This is truly a performance solution whether you are carving canyons or doing high speed straightaways I feel perfectly planted. You can also adjust the suspension if you just want to just cruise. The new Dyna Street Bob is a solid bike stock but at speeds, like most Harleys, you feel like it can do more. This suspension helps you really get the most out of your bike from a performance standpoint. My bike now soaks up bumps, potholes, and railroad tracks with no loss of stability. I used to feel a tad uncomfortable riding at 80mph but now 80mph+ is a nice highway cruising speed. I'm glad I made the decision to do this upgrade to my bike, it now handles as good as it looks. Harley suspension doesn't get any better that this at any price. I already had upgraded rear suspension but with this solution I feel like I have to get something even better to do justice to the front end.


Should’ve done this when I bought the bike. Best upgrade along with rear shocks
