The spring on my ohlins rear shock says its a 1091-21/75 L446. Can anyone help me identify if this is going to be a good spring for a 210 lb. rider? I did a search on google and on these forums and came up with no information. Thanks

Thanks, did you get that chart off of the ohlins site? I am about 96 kg without gear, so is this spring going to be to soft for me?

I had the bike setup for me by the shop that I had some work done at. I am going over the bike to make sure things make sense to me. The sag, rebound, and compression of my bike have all been set both front and rear. This is going to be a track only bike, so I do not need to worry about any road conditions.

For track use your spring will be too soft. Use a 1091/31 i think.

I see you have a speedcell battery, what do you think about this product ?

I could not find a tuner wiling to tune my MyECU, so I cannot use it, but foremost my leaking fuel tank is an issue. Overall I have not had an isues starting the bike. Hopefully after this monday I will be able to give you more infomation because I am supposed to take my bike to the track. Ill keep you posted.

I am running a 1091 -21 75 on the Ohlins and .90 springs in my Showas for road use and I weigh 180lbs.
My brother weighs 250 and is using a 1091 -24 80 on his Ohlins and .95 springs in the Showas for road use.
We may need to add one stock spring (1.0) to his .95 to get a .975 rate (1.0 + .95 / 2 = .975).
BTW, both bikes are 2000 996.

thanks scott. i am wondering if my shop was giving me a softer spring for a reason. he set the ride height and the sag, as well as the rear rebound and compression. I am guessing because I am on the track only he figured a slightly softer spring would be better for feel. I havent taken this beast on the track yet this year afer all this work so I am not sure how it will perform.
