NickisGod Posted April 9, 2010 Report Share Posted April 9, 2010 a few companies like lonestar and laeger produced a hybrid atv chassis during the 2 stroke mx atv days. banshee are only prized because of there twin power plant and unussaly box look. otherwise honda it held down the chassis department. take notice to the rake or diagonal placement of the a arms in relation to the chassis. this rake is also called caster. also the bottom frame rails are mad skinny, allowing more travel and less bump steer. theres alot of difference between the trx and the banshee the "250r geometry" means the bike was built around hondas design but uses yamaha powerplant and plastics Quote Link to comment Share on other sites More sharing options...

SheezFast02 Posted April 9, 2010 Report Share Posted April 9, 2010 nickisgod hit it. If you ever check one out up close take note of the A-arm placement. You'll notice they're set up to travel in a more rearward direction. This reduces bump steer and I'm sure it'd reduce a ton of rider fatigue, say, during a race or a long bumpy trail ride. Since the machine is traveling forward, it only makes sense to have the suspension traveling a little to the rear to soak up alot of the harsh terrain. I don't understand why Yamaha didn't build the Banshee with the same geometry from the factory. Quote Link to comment Share on other sites More sharing options...
AKheathen Posted April 10, 2010 Report Share Posted April 10, 2010 well, actually there are a couple things....the frame rake is just the frame, but basically just a term used to point out the swing radius/direction of the arms. but, it is in no way at all corelated to caster, which is set solely by the relationship from upper to lower ball joints creating the caster axis. you should go do a bucnh of reading in the suspension section, where this is more than covered.....but, to answer you question, you need a full front frame reconstruction to accept new longer arms. it will be a good knock-off of honda handling, but it would be 10x bettter, imo, to just custom build a front suspension that handles to what suits you , rather than just better, for the same price. that's actually what i am doing when i get the materials.......x+a-arm long travel front Quote Link to comment Share on other sites More sharing options...
