The Shinko is brand new put on by PO, it's got so much side wall flex. Riding at 80mph the bike starts to slightly weave....bloody hopeless. I will put on a matching Continental when the stock arrives.

You sure its the tire and not your neck bearings? I've also heard that worn motor mounts can cause a bike to weave like that.

 

These rubber mounted bikes are known for being loose. Replacing the cleave blocks in the swing arm and new rubber mounts will tighten it back up.

There's also an aftermarket brace that connects the drivetrain to the frame to tighten it up.

 

Neck bearings are good.... motor mounts seem okay. If you push sideways on the rear you can see the side wall of the tyre flexing.

 

During the 'vid', I had to get Shinkos. After that I chased handling issues and ended up replacing front and rear suspension.....it was better, but not right like a RK should be. Wore the front out at 6k-ish miles and replaced it with a Dunlop.....wala, no more issues. Now I am getting that weave movement at 80+.....can't wait to ditch the rear Shinko.
Just say no to Shinko.

 

That one you put on your blue and white RK was worse, that ****er nearly killed you!

 

And which tire was that.. Would love to hear the details..👍

 

Shinko, same as the one he has now...but worse, wobbled like it had no sidewalls, which for all practical purposes was exactly what was wrong with it....might as well have been a balloon! Nearly spat him off in heavy traffic..
I remember him sending me a video of the tyre distorting as it sat on the kickstand.

My Bridgestones are like hewn rock in comparison...and in NZ, Shinko are no longer a cheap tyre.
