Nice! .... thanks for this info .... this is really interesting ... given we've had a solid 8 years since the release of the RC51 SP1, have the engine tweaks (mods) lead to 185 RWHP yet with anyone that you know of? I appreciate that a race engine will run super-tight tolerances, basically hand honed internals and beyond ... but to my way of thinking RC51's should be very close, despite age, to being the quickest V-Twins on the scene. Thank you for you prompt replys and time, I very much appreciate it.
Well 6 to 8 years is a lot of time in the technical space race for bikes.
Compare the RC51 WSBK bike to a new Ducati 1098R.
The Honda produced around 185 HP at the rear and rev'd to 11-12K RPM, but required major parts replacement at 2700-3000 KM intervals.
Whereas the 1098R produces 180 HP in street trim with only routine maintenance.
I'm still amazed at the output the Ducati makes, 180 HP and 97 Ft/Lbs of torque. Incredible.
I can only wonder what the RC51's replacement could have been.
We'll probably never know as Honda never had a replacement in mind.
Honda has always considered the V-4 to be the perfect design.
It was a hard sell to persuade them to design the RC51 as a V-twin.
