I think it will look good only if the exhaust pipes go up inside a swingarm.With the stock swingarm like in the first pic it looks ugly.
Oh it is an TL engine for sure!I like it , the tail is a little to high for my taste, I think it's a euro thing idk. You don't see the tail section way up in the air here in the states as much as you do in Europe. I love the styling tho. I'm happy with the angle of the rear as it is stock. I could go an inch or two higher with a narrow tail section like the r1 in the link, just not that high. The rear angle in the first pic is more to my liking. It's just a matter of preference. Looks like he's got an r1 engine in that tlr frame. It's hard to tell but it's not a tl engine for sure.
If you could get me some photos that would be great.my TLR has an R1 rear end done by the previous owner. Its a cut down TLR subframe with the R1 tail unit over it. The seat is a bastardised hybrid of the R1 attached to the TLR seat base to use the original mounts.
I'll try and dig out a camera and get some photos of it at some point. The bike has unsupported danmoto exhausts which look awesome as they run parallel to the R1 seat unit.
