In this topic you can follow the progress of the development of our Tube Buell S1,S2,S3,M2,X1 rear shock . We will make them for all Buell Models from 1984 till 2010 Tube Buells, all Buell XB models 9 and 12 models and the Buell 1125R and 1125CR.


Below you can see our prototype of the Tube Buell rear shock as it started:



Afther that we made a prototype:















After that we mounted it on a 1995 Limeted Edition Buell S2.






Then we took here for a long spin 80 miles for the first expression. Wow, very very good response. I use a 85-95 kilo spring, and because this is our test shock, we didn't mounted the remote reservoir. Save time. I went for a 80 mile test ride this morning, and did high speed corners, low speed corners, 8 mile very very bumpy road, still feel kidneys, low speed and high speed round abound, very high speed highway, a lot of adjustments and can only say what a brilliant product. I use as a reference a older AST aftermarket shock, with a remote reservoir and this simple shock without the remote reservoir is giving me much more feedback (or better said feels perfect). I set the spring adjustment to the original shock height and played with the adjustment but all i can say, let's go in production.



Because the feedback of the shock is so good we will make a version with and without remote reservoir. For the average rider that is more than enough adjustment for even a few times track use in a year and pleasure riding. We will then also make a version with a remote reservoir for the compression, But as far as i can feel it will be perfect for 80-90% of the customers who rodes a Buell S1, S2, S3, S3T, M2 X1 when we make them with a tailor made spring.





I rode her hard when she was warm, I can only say I really love our rear shock. Have a look at the tire, Do i need to say more.





Update 13-3-2012


And this morning it was cold, i put another 60 hard twisty test miles on the shock and played with adjustments, I keep loving it more and more.
