Ok, a little different approach here to the topic of improving the ride on the SlingShot. I related a more detailed description in other threads, but an abbreviated version is that we replaced the front tires on the Grasshopper today with Yokohama-yk740-gtx tires. Though our purpose was concerning a different issue, the absolute biggest surprise was with the difference in ride the new tires made, which is no less than amazing. Before the Grasshopper had definitely what could be described as a "choppy" ride. With the Yokohama's that "choppy" ride was transformed into smooth and much, much more comfortable. The difference was so dramatic that the first thing I did when arriving home was to check tire pressures to assure the front tires were not underinflated. So, before purchasing those aftermarket shocks, a cheaper alternative may be to simply try a different tire?
