Has anyone installed a Yamaha YZ450 motorcycle twist grip throttle on their new 450YFZ yet?

What is the cost of the parts (twist grip throttle) and are there any other manufactures making a twist throttle for the new YFZ?

Anyone have any pros/cons of moving to a twist grip throttle from the thumber?

 

I don't know the cost, but Kory installed one on his race bike. He used the stock YZ450 twist grips and cables from Yamaha. He had to drill and tap the carb (it has the spot for the cable, but it is pluged)

I have not heard of any one else making on yet.

I personally don't like them. but know some guys that do (most are MXers).
