I saw this at my local motorcycle shop today. Norton Commando with rotary engine.....
It was rated at 588cc, so had a fair old advantage over 500cc opponents ? !!Matt Spencer said:THAT engine assy cleaned up in English Raceing for a time .
gripper said:The 92 bikes developed 130bhp but the 588NRV developed by Brian Creighton in 2006/7 pushed out 170bhp @11,500rpm and weighed 130Kg dry. Unfortunately they failed to perform at 2010 TT with a series of problems. I believe the variable venturi intakes involved a mechanism from a ATM "hole in the wall" type cash dispenser!!
As long as the rotor housings are in good condition (they can get chatter marks on them) the rest can be fixed relatively easily. The end plates wear but they can be thermal sprayed and reground. Other than that you could almost think of it as a two stroke Commando without the isolastic system. Some of the seals can also be replaced with cut down Mazda ones which are probably better than the Norton ones, or aftermarket Mazda ones which will be better again.OttoElPiloto said:Hi there.
I was reading about Norton rotary engines and i found your blog... ¡cool!.
I am buying an original Norton Interpol II right know, (the rare Police unit you know). Just to deal with it, I am more a cafe racer bikes guy...
What do you think about this bike? Is that engine so difficult to take care of it?
