Yamaha XS650

CYCLE WORLD magazine June 1980

Yamaha 650 owners tell us their machines are motorcycles. “You remember motorcycles.  They have a pulsating throb instead of an electric motor whir …. They’re narrower than your car …. You can actually adjust the valves without removing the camshaft. Just one camshaft? …. gas tanks with curves instead of bends ….  a strange looking lever on the side you can kick to make it run …. something you’d feel uncomfortable wearing a suit and tie on …. They let you park it with the Harleys down at the tavern.”

So, I made an interesting discovery today….. In my never-ending quest to find some good rearsets, my friend had an idea of chopping off the original mounts and drill/tap wherever I want to put new rearsets. Trying to get a visual of what that might take and what it would look like, I grabbed some rearsets that I had laying around. A customer bought these off of ebay and it turned out they were wrong for his year. It turns out, they fit PERFECTLY to the original rearset studs coming from the mount. PERFECTLY. So, if anyone here is looking for some rearset solutions, these are for the 2003-2004 Kawasaki ZX6R. NOT the 2005-2006. Sooooooo… Looks like I got some rearsets! 20190115_120625.jpg 20190115_121529.jpg
