Hi guys. Just joined the group as I have bought a ZXR250A to play with a little bit. I have two engines and one will be race built. Looking forward to the dyno tests!!. These are really rare motorcycles in Spain as they had not been imported back then. I take the opportunity to ask you about the shock length for this bike. This one looks very low at the rear. Would anybody be so kind to take a measurement from the rear axle vertically to the lower edge of the fairing and let me know??. I have attached a Honda RC51 intake valve on a ZXR250 head or in a barrel!!. Amazing miniature engine!. Thanks!!
