What a difference! Bike never rode better
Bought this set a few years ago for an rt I picked up cheap. The shocks were both blown on it so after a bit of research, I bought this set.
Didn't think much about them, they worked and the bike was fun to ride.
Fast-forward a couple of years and I find a really clean rt with less than 30,000 for next to nothing. Riding that bike with the stock suspension was less than confidence inspiring. I switched the hyperpro stuff over to the new bike and it truly made a huge difference. I can happily grind the foot peg feelers around tight corners with confidence. The bike is now fun to ride. It's amazing how bad the stock shocks are or how good the Hyperpro units are? Either way I'm happy with these.
If you have an old rt with stock suspension buy these, the bike will become much more fun to ride.
Good experience from EPM, came recommended and did not fail. Took some 3rd party parts to install on my KTM 990 Adventure and did a great job plus servicing..
Easy to install. Fit perfectly. Looks nice on my bike. Good quality. Took the factory shocks off. My bike rides much better with these shocks on.
Easy to install. Fitperfectly . They look nice nice on bike. Good quality.
excellent upgrade from a worn out softie on the rear of my 1988 Honda NX250
Great communication. Had a custom one done by them for my drag bike and it's perfect. I've had it a year now and what a different. Best deal for a perfect shock. Definitely recommend!
This set up has been everything I was expecting for the WR250r. The 461 shock with reserve mounted easily per instructions as did installing the progressive fork springs and oil. Your calculations on spring weights and oil viscosity for the riding I described has been great. Added 3/16-1/4 inch of preload on rear and now I just need to recalibrate myself. Rear tire puts power to the ground so much better. Keep up the great work! Andy
