jon haney Posted October 20, 2008 Share Posted October 20, 2008 Anybody have any extensions they want to sell or know of any new ones that are cheap? Quote Link to comment Share on other sites More sharing options...
TJ1137 Posted October 20, 2008 Share Posted October 20, 2008 I have looked at these in the past, but I still question their safety as far as holding up. Anyone have some input on these?? Quote Link to comment Share on other sites More sharing options...
blackhawkxx Posted October 20, 2008 Share Posted October 20, 2008 My son uses them on his CBR1000RR and races about every weekend in the summer. Never had a issue. Quote Link to comment Share on other sites More sharing options...
Furbird Posted October 20, 2008 Share Posted October 20, 2008 I know several people that have used these at my local track long term and never had a problem. The only issue I've heard of is legality. It forces you to go over 60" wheelbase on Birds and Busas, which takes you out of a lot of "streetbike" type races. The reason is that your rear axle cannot start until about an inch past where your current adjuster bolts are on your stock swingarm. That puts you at about 3.5-4" over stock chain adjustment range as a minimum. The bird is 58" stock wheelbase if I remember correctly, so you're at 62" approximately on the tight end. The breaks are 60, 64, and 68, with 68 being around Kent Stotz' bird range. Quote Link to comment Share on other sites More sharing options...
jon haney Posted October 20, 2008 Author Share Posted October 20, 2008 The classes I'm racing in (Pro ET & Super-gas) don't have any limitations. I thought about having the swing-arm extended, but I would actually feel safer with the bolt-on's and I would also have a heavier duty chain adjuster.
