I would advise staying away from Metzler. I had three Metzler 880s fail on my Vulcan 750 at fairly low mileage. Pieces of the tread just came off. The Rebel is not my choice for sport type riding, due to poor handling. That's not the Rebels fault, it's a cruiser. I'm planning to build an XT225 based supermoto. I can't ride a sportbike due to the ridiculously low bars and high rearset pegs. Not only super uncomfortable but dangerous. I lost all the feeling in my legs while riding my former Kawasaki EX500 Ninja, which is not even a real sportbike.
