No its a light flywheel, short stroke, light piston and a decent valve train that doesnt float at revs. Add that to a light alloy block and a light machine and you have speed. Its all about revs, more than 10000 is the go.
This all comes packaged in a motorbike frame. When you can light the back wheel up in top gear with a flick of the clutch, thats power. All this for around $12000 in a bike shop near you.
Your preaching to the choir here. I started off on a CBR250RR (18k redline) followed by a VFR400 and then a CBR1000RR the week they were released in shops. Then I got converted to Motards (KTM 640 and 690) and picked up a VTR1000SP1 for the hell of it. I also spent 4 years as Service Manager at a Dealership where I got to ride everything with 2 wheels. Been through a few dirtbikes as well. Currently have a WR250R (enduro) and a WR250X (motard) in the shed. Main reason's for the 250's was preservation of licence and cheap rego. The missus can use both as well. There was one stage where there were so many different bikes in the shed it was getting ridiculous so we decided to cut back.
the real fun it pulling up next to somethig like a Ducati 900 (in your car) and smoking them
the look is priceless
Blocker do some research into the old Commodore cup engines. I just read they made around 300hp using red motor heads. 300 hp from a 253 is not too bad at all.
Here is a link with some info.

Yeah remember they were going to do it then I went overseas and never saw the actual article.
350-400hp from a 253. When you compare the 253 to a 250 Ford 6 instead of a 308 (which was the motor they were up against) you really have to say they were a greta motor. I dont know if you can get 350 hp from a 250 6 but I suppose anything is possible.
