will an R1 shock fit my 99 thunderace?

Any replies appreciated.

Is there leak or what kind of problem with original shock?? I have not seen any problems with my original shock and just wondering how you get it broken. Original shock can be opened and fixed and if you do that I recomend change oil to litle bit thikker and spring to 10 or 20 points harder. R1 lighter than T-Ace and I don't see that it will work better. Also did you know that original shock is originally made by Öhlins??? Yes there is no text Öhlins but it is. I have talk with one mechanic who is lisensed Öhlins repairer (best in Finland) and he's comment was that oly change spring and oils (he also sell Öhlins and WP). So first try to find out some who can fix that old one and ask that prize and after that compare is it better solution that new shock.
