The 52T rear won't fit a Yamaha Warrior
The 52 tooth rear sprocket will bolt onto the place it is supposed to, however the chain guide's steel bracket is so close to this sprocket that it won't allow for chain adjustment, making it impossible to use the 52T sprocket. I suppose one could use this but it would require cutting and welding the chain guide mount and fabricating a completely new chain guide. I'll use it on my 1981 YZ250 instead since steel JT sprockets have always given me good service.
Nice product for a great price.
Changed down to a 15 tooth sprocket, from 16 on my 1998 Honda VFR and can feel better acceleration throughout the range. May have lost a few mph on top end? The fit of the part was excellent, didn't have the rubber insert of the OEM part possibly a little noisier? Was a 15 minute replacement.

Fit very well on my ttr 90 and rides smooth.

The sprocket is strong, but you're sacrificing that for weight! These are much heavier than aluminum sprockets. It should last considerably longer, though, and it was cheap.
