It's only when I really start to push things hard on the throttle exiting some corners. The stock swing arm does an excellent job but it's at its limit. The excellent grip and stiff carcass of the Dunlop GPRacers gives great feedback. I'd be pushing things to the limit ( and I ain't going there ) once this swing arm is fitted to find similar chassis flex.coxylaad wrote:What's the stock one weigh?
Are you finding the limitations over the stock swingarm now?
Alan Cathcart had Over place in extra bracing on his Swing arm from the brace to the pivot but I ain't going to push things that hard on mine..
The stiffened swing arm just drove and chassis flex up into the frame hence why the diagonal brace he had on the frame under the tank. But remember he was running a 6.25" in world class competition racing where the limit is where you sit constantly.
I feel a 90 HP TRX is still well and truly capable of running the std swing arm even with a 5.5" rim fitted in there.
I can see so many advantages in weight alone by fitting a later model lighter R6 5.5" rim into the stock swing arm compared to the YZF 750 rear end conversion.
