cabby Posted July 21, 2011 Report Share Posted July 21, 2011 What effect does a flywheel weight have upon a trials bike and what would be the reason for fitting one ? Quote Link to comment Share on other sites More sharing options...
alvin123 Posted July 21, 2011 Report Share Posted July 21, 2011 It stops the engine from spinning as quickly. It will smooth out the power, as it will have greater momentum. Grip in sand, mud etc will be increased too. I guess it depends on what type of trials you ride. If you ride rocks, big steps you need the bikes power instantaneously, I ride sand pits etc I want smoother power delivery. Quote Link to comment Share on other sites More sharing options...

alvin123 Posted July 21, 2011 Report Share Posted July 21, 2011 It's about having a laugh and fun. What bike have you got? Quote Link to comment Share on other sites More sharing options...
dombush Posted July 21, 2011 Report Share Posted July 21, 2011 Think of it as a throttle lag device. It just marginaly slows down the engine's reaction to you opening or closing the throttle... effectively increasing the inertial affects. It has most effect when the rider requests sudden large increases in revs. Good effects are as the previous post describes, plus making the tickover more stable and resistant to stalling. Bad effects are:- --- that sometimes you want "snappy" acceleration and deceleration (wheelie over logs, rock steps etc.!) --- the rear wheel can lock up / drag easier when entering a steep slippery downhill slope with no throttle (when your expecting the engine to increase revs to help slow you down).

nigel dabster Posted July 24, 2011 Report Share Posted July 24, 2011 I had a 290 evo and could not use it with a weight on. It comes down to throttle control if you are good with that there is less need for it.As it takes the sharpness of the accelaration it has exactly the same effect on deceleration and runs on.
