    250cc 4 stroke riders can now race!!

    I just remembered that during prize giving at Vic club on the 24th of July 2004. An announcement was made that 250cc 4 stroke bikes will be allowed in with the 150cc street stock bikes.

    I can't remember the full details but if there is any interest here, I will find out more.

    Cheers, MR.

    Seems a bit unfair doesn't it ?

    I know that some 250 fours can do in excess of 190km/h - I might be wrong but isn't an RG150's top speed about 170km/h ?

    What are the comparitive acceleration/handling stats ?

    Wicked, might look at getting some race glass for my bike then.

    Yeah, my bike is limited to 180kph but I doubt there are many places where that will make much difference. The major advantage would go to the RG's 50 odd kg's saving in weight, can corner alot faster than my overweight pig.

    Rg150's will do 180kmh

    Sounds good to me. Might encorage more newcomers to raceing if the've got a 250cc road bike already.
    And the more riders in the class, the more likley you are to find someone just at your level to race against

    According to them it is fair after doing an experiment. They got a good racer to do some laps on a ZXR 250 or something similar and then a few laps on the RG150. It was pretty evenly matched at the end.

    I guess the RGs can make up for the speed they don't have in the straights in the corners.

    It's great I reckon. Before, it seemed like a waste to have all these race rep 250s there and not see them in use at their full potential (apart from seeing Andy1 ride his 250 of course!).

    Sweet. Would be another option for budget racing.

    Well at taupo and manfield it should be fair.... but at puke it is a different story, there was a guy who was bloody fast on a CBR250RR, he was doing 1:18's and my best is 1:20's although after tonight when i do some rearset mods, i should get 1:18's hehehe..... 250 fours have a slight amount more acceleration and top speed, but the RG does have more corner speed (until the pegs scrap )

    Do the RG's have more corner clearance than the CBR's? I would have thought they would have.

    Na they don't, CBR's actually have a lot more corner clearance.

    but if you hang off like a monkey ground clearance can be percieved to be larger

    well, i cant do the mods without making a whole new rearset so it looks like angle grinder + peg = ground clearance.....

    YAY!!!!!!

    I talked about the likeliness of that happening at the KB BBQ with KK and he agreed that there wasnt anywhere to race my ZXR250 competitively.

    YOU HAVE ANSWERED MY PRAYERS, I NOW HAVE REASON TO FINISH THE BIKE!!!!

    where opinion holds more weight than fact.

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.

    The RGs don't seem to have enough ground clearance. A good trick when racing them at Puke on my bucket was to follow them into a sweeper, wait till they scraped and ride round the outside of them. The bucket seemed to have a weight advantage under brakes as well. Brilliant fun, the RGs were fast enough in the straights that you had to try real hard everywhere else to keep with them. The new bucket though . . . . RG
