Upgrades of any kind for race bikes? I know they make inserts to go into the bushings but is this sufficient enough for a track duty? Anyone know what the old tube frame AMA bikes used to run in the swing arm? How stiff can I make these bushings? Im sure it must need some give, but how much is to little? | ||

Install a set of these  Into your rear Iso's  And be prepared for the the scoot to do the Texas 2 Step at idle,best for the bike not on incline or slick Concrete without rider supervision. lol I still have a couple sets if your interested. | ||

They will make you BUELL VIBRATE like a "SPORTSTER" !!! Put them on my 97 S3T because the early rear isolators were not strong enough to ride two up and they made my tail section start to break up !!! The later rear isolators could handle the two up weight !!! | ||

pingel makes/made these as well I put a set on my tuber | ||

I run those on my original isolators... and i'm sure with the amount of wheeling and stoppies I do, its the only thing keeping those isolators from destructing... however I believe they are too stiff. Id rather have the same thing made of a nice high durometer polyurethane. | ||

jramsey check your PMs  | ||

Seems like I remember a pretty good rider track testing these, and found that there was a VERY small decrease in lap times and a massive increase in vibration. If you're just doing track days, don't bother. If you're racing, and you're coming in second by a tenth of a second, go for it. | ||

You must take into consideration of old isolator. Vs new. | ||

One other depressing reality: I remember vividly when my X1 was new, I had that "Fuell" magazine for a year and they posted AMA X1 series race results. LOTS of DNF due to engine failures. Made me look at my new X1 like a time bomb. After 30,000 miles, I started to relax. Hate to be Debbie Downer but they are sportser engines. They take a lot but keep it at 7000 for lap after lap and......  | ||

The vibration isn't that bad. In my case it doesn't smooth out until 4K rpm instead of 3K. No biggie. The rear end definitely squirms around less and I like feeling what the engine is doing. It is still silky smooth at high rpms. My years of jumping railroad tracks cracked both of them at the thinnest points. I'll have to fix that one of these years. I did have to find a new tail light solution as both the tail light and support bracket would self destruct periodically. Jramsey, what's that small threaded hole about? The AMA Pro Thunder class had occasional DNF's due to catastrophic engine failures. They tended to be tuned on the wild side. The Lightning series bikes has a much milder tune and seemed to hold up a lot better. I was at the last Pro Thunder in Daytona...which also featured the last of the AMA 250 GP's. I feel fortunate to have been there to see it. | ||

Rick the tapped hole is there to facilitate removal of the snubber when needed. |
