A 90 HP Versys???

Well, not actually a Versys....
Not really a big Flat Track fan, but was reading this article and about 3 paragraphs in, it got a little more interesting....


If that thing is putting out 90 HP I am pretty sure "Daddy's little girl ain't a girl no more"--It's got to be bored or stroked or both, but I bet it's not a 650cc engine anymore (the article pretty says as much "the smarter tuners knew, that taking little engines and making them bigger and better was the way to go."), particularly if the limit is 1,000cc and it sounds like they are up against 750's....I wonder what it is??? 750cc? 800cc? 1,000cc?

Ride to live, live to ride.

Interesting. I would be worried about reliability with a 90hp race motor though. I haven't heard of anyone stroking these engines yet unfortunately. I would definitely buy a stroker kit if one was offered

I'm pretty sure they are getting close to 100bhp in the super twin (or lightweight) class of Irish road racing. Their bikes are based on the Ninja 650 motor or the SV650 Suzuki but most are the Kawasaki.

On the Isle of Man James Hillier averaged 119.130 mph (191.72 km/h) for a single lap of a four lap race. They have to keep them at 650cc and must have the engine out of a bike that was for road use sale. Ryan Farqhar has set up KMR racing and builds these bikes for race use and from all accounts they are tops.

On a little side note about Ryan Farqhar he holds the record for road race wins. Even more than Joey Dunlop. He decided to retire in 2012 after his uncle crashed at the Manx GP on a bike Ryan built for him.

Falling down is your bodies way of saying you just screwed up.

That engine makes way north of 90bhp

I know Ricky quite well as he is a buddy of mine. I've been around the whole project since its inception. One of the reasons why I own my 2011 V

The engine(s) in the bike(s) have been detuned a bit from what they are capable of making. They needed to do this so the bike would hook up and not spin all the way around the track and ruin the tires in just a few laps. In race trim they make about 95bhp at the rear tire (for the Mile events). The original engine Skip Eakin built was making well over 100bhp, but was unrideable on the dirt. They started detuning the engine and adding rotating mass trying to make the bike work and it succeeded. Between Ricky's chassis and Skip Eakin hp that bike was always a threat on the bigger tracks. The engines as raced were 750cc. This was done with both oversized pistons and longer stroke.

Watching Bryan ride that bike was just a thing of beauty. Now the bikes are just expensive furniture inside of Ricky's home.
