i have an 06 x and its an amazing machine, i have over 6500 km on mine, and i only took out the top end but it was my fault, broke a oil injector valve off when i put the motor back in after fixxing bulk head , didnt relize what i did at the time till the piston seized
seat clutch, and rebuilding shocks, and i think the steerign post but could be wrong on that, i got the adreniin clutch (the fugger riped me off) in mine, but gunna be putting a team in this fall
its the 440 race seat with a grippy cover and no storage and yes its alot light IMO, im not sure but must adreniline i see have a steering post with handles bars with the riser built in sort of say if you get what i mean
The '06 x sleds came with a 9 tooth driver and a 2 1/4" track (powdermax without huge holes in) probably the best stock track out there, pull out the 21 tooth top gear in the chain case throw in a 19 and your in business.
or put 7 tooth driver to fit 2 1/2" paddle and run polaris primary and team secondary piped and reeds and you have a serious contender trust me, that is the best setup i have tryed yet.
