Yamaha TRX850 Enthusiasts Forum

Hi All, i'm new to this site, and would like some info on fitting the YZF750 swing arm in my TRX, i see many people have done this conversion, can anyone please give me any info on mods to the swing arm if any needed to fit to mt bike?.

I have the YZF swingarm, but it came with the bike. But from what i have read and heard, it is a simple bolt-on thing. where you might get problems, is getting the chain to lin up. If you're using standard TRX rear sprocket, you should be fine by reversing it. (As i have read and heard...)

Hi, when you open the..[ TRX Mods and Upgrades ]..page you will see a SEARCH box at the top of the page , click that and you will have all the info you will need..and it IS easy.

Dead easy modification. The swingarm is a straight swap for the TRX item, but you need the YZFwheel and spindle to go with it and you will need an offset front sprocket (moved 4.7mm further outboard) and 1.1mm thick washers behind the rear sprocket to get both front and rear sprockets properly lining up with the YZF chain guide. Its much easier than it sounds.

Many Thanks guys, just the info i was looking for. i pick up a complete arm wheel etc on sat, so shouldnt be long before shes back on the road.
