It's very possible it has different sprocket, and it could be weight biased towards the rear, notice how unstable the front forks are, way more than it should be, it has headshake way to much, for the proper weight distribution. Even a SV650 n will do that if the rider is sitting on the rear seat. lol
Son compteur semble donner à peu près le double de la vitesse réelle! His speedometer seems to give twice the real speed! Don't know if its because off a lower gear or a unaccurate speedohealer!
