Yamaha did a lot of work with this crossplane crank engine, and Toprak seem to be enjoying the fruits of this work.

It sounds just amazing.

Indeed, very informative video here explaining inner workings and pro's and cons. Not an easy motor to build but the Japanese are up to it. Liked that bit about the NSR Big Bang as well 18:00

That big bang relation to the tyre slip was interesting.

I quite like that, just as much as I like the Harley Davidsonís of my neighbours that sometimes sound like it misses a beat and about to die but just keep making music.

Cold start is quite strange also. You press and hold the start button a second or two, enjin turns over, let go starter button and Bwah ! it fires into life. Best way to describe it then, is it sounds the way it looks like a duck waddling  :lol8:

Sounds fantastic!

They basically took a V4 engine and made it an inline 4. Brilliant!

Loved the three V4 Honda Sport Tourers I had.

Is it not the other way around?
Inline 4, with V4 characteristics?

Wanted to say the CP4 sounds a lot like a Honda VFR.

No wonder the T7's CP2 motor is such a brilliant mill!
