I test rode a Tracer yesterday.
it is a very impressive machine - very sharp, lightweight, fast and nimble, with quite a sporty character. Seems well built too. The engine revs up fast and feels and drives much like a four-cylinder but with a big dose of torque at the bottom end.
However, you very much sit 'on' it as opposed to sitting 'in' a TDM, and I felt exposed with a lack of fairing at the front. Not a particularly relaxing ride as it is quite aggressive. Wind blast was bad, and foot pegs were positioned for enthusiastic riding. I'm all for sports bikes and I do regular track days on my CBR and ZX7R previous to that, but I have the TDM because of that way the TDM is, and I don't think of the Tracer as a TDM replacement; it's more of an upright sportsbike. I wouldn't swap one for the other either way round. I would, however, swap the Tracer for sportsbike and vice versa.
Full throttle in 2nd lifts the front wheel though - that was fun
