hi all cracking site,lots of info can anybody help me,i have a 2001 yzf 426 and a 1999 wrf 426. the wr seat height is smaller then the yz,not usually an issue but im 6ft 5 and feel a bit big on the wr. i was going to get the higher seat foam but after lots of measuring im putting the height difference down to the subframe. have i hit the nail on the head or can anybody point me in the right direction. if this is the issue is it possible to fit a subframe off a yzf to the wr and is it a straight swap. any help would be lurrrrvly.
