I suspect the final drive was moved to the right because of reasons of how the transmission was incorporated into the unit design. It appears from the photos that there's more room in there for the chain than the old Bullet had. Remember, when the old Bullet was designed, there were no "o-ring" chains!
Regarding the comparisons to the new Bonneville, I've noticed that happening too, and I've even mentioned it myself.
Here's what I think,
I think the old Bullet has enough power to do whatever I want to do, but I didn't realize it until I actually got on one and rode it. The specs are misleading, because they make you think that the Bullet is slow, when it is quite adequate for most purposes that a 500cc motorcycle would be asked to do.
Regarding looks, IMO there is no comparison whatever.
I went to the Atlanta Motorcycle Expo a couple of years ago, and was intent on seeing the new Bonnie, and also the Bullet.
When you compare them side-by-side, the Bullet totally obliterates the Bonnie in appearance. Not even close. The Bullet looks like a jewel, and the Bonnie looks like a rhinestone.
Sorry, but i calls 'em as I see 'em, and the Bullet and new Bonnie were miles apart in visual appeal. The Bullet looked like it should be the more expensive bike.
My desire for a new Bonnie evaporated instantly, at that moment.
If the new UCE Bullet looks even more improved, or even equally as good as the old Bullet, then it's no contest.
