I don't/won't pretend to know alot about suspension science, but i can share my thoughts on the Penske 8987 i've just had fitted to my 2007 yamaha r1.
I've done a write up on the r1 but this shock deserves its own thread
Mid last week i had the shock fitted. Straight away the difference was incredible.... its hard to explain the difference/improvement over stock, its just what the bike needs.
The bike now doesn't squat and wallow about under power, it just hooks up and powers forward with minimal fuss. Riding on roads i've known for years i found myself feeling safer due to the increase in grip.
The stock unit is like a pogo stick in comparison
I did find the setup a bit to harsh for "normal road riding". A bit bumpy and skippy. This would clear up with more aggressive riding. I thought i'd try it as is on the track then ask Shaun about dialing out some of that harshness for road use.
The 8987 was superb on the track! I could not fault it. I found myself able to get on the gas earlier, i can't explain why... must be just the extra grip and confidence it gives.
So back on the road:
The setup is a little harsh and skippy but i love the way it doesn't squat or wallow under power. Shuan makes some suggestions, i back the high speed compression off and the harshness is reduced yet the shock still performs as it did before.... its still firm in the slow speed stuff (squat, under power) but soaks the bumps on the rough roads heaps better......
The low and high speed compression damping adjustment on this shock gives the best of both worlds, its impressive.
I don't really know what else to say. I'm very pleased with the shock's adjustably, performance and price. Shaun has been very helpful and easy to deal with (pretty cool being able to txt a I.O.M legend/freak for suspension setup tips while out on a ride, i recon).
Thumbs up. Thanks Shaun.
