The most dominant, all time winningest racing vehicle of any description (bike, car, airplane, boat, submarine, camel) in the history of this planet was a 45 degree V-Twin, with a better than 45 year record of near total domination unmatched by any other racing vehicle.
The 90 degree V-Twin, on the other hand, has some pretty serious packaging problems in a motorcycle chassis. The motor itself is fantastic. It does, however, reduce the "sum of the parts" to a lesser "whole". It forces the motor to be too far back, it forces the wheelbase to be too long. Both affect handling and acceleration to a very negative degree. Motorcycles are not just motors, and the motor planform has a much greater impact on other design and performance elements than just its power output.
