Which is the model no one intending to race or track an R1 should buy. We've prepped more than a few Ms and the customer always has the same look on their face when they bring almost everything they paid an M premium for home in a box instead of on the motorcycle, including the mechatronic "MotoGP suspension" no Yamaha (or any other brand) actually uses in MotoGP. The brushed aluminum tanks are cool, but the M is the street cool and that's about it. On a race track, the premium price amounts to fuck all in performance. Get the base model R1 (not the S) if you're going to put it on a race track and save yourself 8 or 9k.
