More than a decade later, Shiozaki and his team brought similar properties to the RC211V. The V5 engine layout was inspired by the MotoGP rule that limits both four- and five-cylinder bikes to the same 145kg minimum weight. Honda quickly decided against a single or twin due to their lower performance; and against a six because that would have meant a weight 10kg above the 145kg figure for fours or fives, making tire problems likely. Having narrowed the choice, Honda went for a V5 instead of V4 or a lighter triple, mostly because the engineering team fancied the challenge. Five cylinders would give more power than four; indeed, the RC211V's 990cc unit not only produces close to 220 bhp at 14,000 rpm, but does so with impressive and controllable torque from low revs, as well as being relatively easy on rear tires.
