It’s the best stock shock out there. All kinds of adjustments can be made compared to the gsx. It completely changed my bike. Before the shock change my tc would blink constantly in the mountains, now I never see it at all. I believe the stock shock was so stiff that it was bouncing under acceleration, now it just bites.What's the deal with R1 shocks , are they better than our stock shock? I owned a few Yamaha's and I always changed the stock shock.
