500cc Supersport.

Just curious, what kind of hp does a TZ 250 make? My Aprilia 250 cup made about 60... The KTM and Honda are in the 55 range?

250GP bikes will normally make 70-75 hp in stock trim, depending on which generation/age, and state of tune. Then there's hot-rod parts out there for sure, and lots of gains to be made based on real tuning (case stuffing, head volume & squish, fuel and exhaust, etc).

Ok. Can someone explain to me the note? NOTE: Ducati/Bimota/BMW Supermono/Woods Rotax are excluded from this class


It doesn't mean that all Ducati, Bimota, BMW Supermono and Woods Rotax bikes are excluded? The only "Supermono" style bike Ducati ever made was the Hypermotard and that doesn't meet the displacement requirements. Bimota is the same. 

Just not sure what the point of the note is if it is supposed to mean motard style bikes only.

Gino, TZ250 is in the high 70 to 80hp range.

[roadracer162]

My 1991 RS 125 had 40 HP and I would speculate a 250 would have 80 HP.

I would expect the "Note" excludes the Ducati, Bimota, BMW, woods to tax motored bikes from this class

Not supermotard, hypermotard, etc
It is specific models made for a world superbike class called SuperMono Cup.
Here is info on the Ducati model

So the Honda and KTM are very similar in power to weight.........  ::)


Now I just need to sell our Ninja 250.

Thank you for clarifying that.

This conversation is the reason Spec racing makes so much sense. Simplicity. A rider knows exactly what to bring, and has the exact same tool as the front runner. Leaving the only variable the rider.

I like the intention of the 500 Super Sport class, but I feel it should be designated as a spec class for the CBR500R (or any other major manufacturer that decides to produce a 500cc liquid cooled non Desmo 4 valve twin) in line with current AMA Harley Davidson / Vance & Hines Sportster 1200 class requirements.

I agree that if the true spirit of this new feeder class is supposed to act as a stepping stone to the larger classes, the emphasis should be establishing a MODERN base motorcycle so rider talent is highlighted.

Considering the RZ350, FZR400, and RS250 as options loses the true spirit of the class.  In that case, the class should really be relabelled as ULSS (Ultra Light Super Sport) because based on Super Sport rules and displacement limitations, that's what it really is.

When I started in 2000 the class was called Lightweight Sportsman,the rules is very similar to the 500 supersport class of today.

Does anyone else think an ex500 would be competitive? Looking to get into my first year of racing within the next year or 2 and I have an 2005 ninja 500 sitting at home.

[apriliaman]

I do have a EX500 streetbike also but never raced it.Can it be competitive?It has to be supersport rules. Well depends on how many bikes there will be .I think it can with the CBR500.Don't know about an FZR400 as that bike will have a top speed advantage maybe 10 mph faster but less torque out of the turns.It does have an 18 inch wheel in the back so rear tire selection isn't as good.
