Although rider weight makes bigger difference. Select GSX-R shock with spring-rate you need for your weight. Having adjustable damping allows for fine-tuning that’s not possible with any factory shock. Factory dog-bones can be re-used. Some spacers are needed to widen their spacing to clear larger springs on GSX-R shock.
Here’s preload adjuster for SpicyCactus. They allow you to set ride-height/sag of suspension so it operates in optimum middle range. Won’t bottom out on bumps or extend fully on rebound. As new rider, I recommend not focusing or spending too much on hardware upgrades. Spend it on track-time and classes as that’s where you’ll make biggest improvements. |
Those look like the same ones I have on my 400, they were from China as well. I think they were a little over 20 bucks, I wish I would have went with some red ones. Maybe I will change them!
