If your purely looking at the better V2 engine it depends what you want from it.
The VTR is a great engine. Typical V2 delivery with loads of torque where you need it and revs less than the Suzi. My bike made 107BHP ATRW on the dyno with a full stage one tune (filter, cans, jet kit etc...)
The TL has stacks more power and is more linear in delivery. Up to banning speed id say the VTR wouldnt be far behind the TL. After that its toast

It has more shunt throught the range.
The TL I had made nearer 122BHP ATRW with only a pair of aftermarket cans.
