Bike Info

CC:
400
Bike Description:
This is the Cafe racer "Version R" one with the Cowling fairing and two piece exhaust. Aftermarket CBR400RR Gull Arm end cans are interchangeable! The headlight bulb is a special one, slighly different to an H4 and cost the earth to replace (£45) from Japan. Luckily an H4 will fit with minor modification to the bulb, light pattern is a bit odd. Sprocket teech are 15 front, 45 back and 112 links compared to a standard NC31 of 15,42 110 links.
