Larry Fine, Jim Van,
I can’t say I’ve experienced any handling issues with my ST but for almost as long as I can remember, vibration through the right handlebar( the twist grip) has been VERY troublesome to the extent that after perhaps 1hr. of riding I have to take my hand off the throttle for (depending on traffic etc.) my hand to recover from the vibes.
After an hour of riding, I HAVE to do this maybe every 15 mins. of riding.
The high frequency vibes can become almost painful and is the only fault that I find with my ST.
