Small update..slightly un-seen consequence.
The inner flange of the new grips..and I would venture to say most aftermarket grips, is, no where near as stiff as the inner flange of the OEM grips. I ride with my thumbs fairly hard against the inner..so the grip flange "gives" towards the controls area and rubs it..no big deal at all..except it slows the throttle action significantly..for me, it may make the OURY's a deal breaker..
I'm thinking possibly ATV style grips would be an improvement since they don't have the inner flange like a motorcycle grip.
If you don't hug the inside of the grip like I do, you may never notice this.
