"Spoken from a guy who has tried the AHRMA GP200 class with a 160, I have to agree with Chris. The Yamaha CT175 and Bultacos are just too damm fast for us to compete on an even playing field in GP200. They make something like 35 horses to our (maybe 15). Sure is fun going around them in the first couple of turns though, until we hit the first long straight away where they disappear for good.

I hear that there is some guy, however, riding a very modified CB175 back east and doing quite well for himself. Only problem is that you wouldn't have any fun in the F160 racing which is what we all do it for. Other solution... Build two bikes, one stock F160 and the other, a monster bike!

Have fun,

The CT175's are legal in AHRMA 200gp? That's a 1970 and up bike. They run in ULWSV in the USCRA. And there aren't any 175 bultaco's making 35hp that I know of. Turk's 250 makes about 40hp though.

Gimme a couple more years...then Clever Dog will be feared....right now we are just annoying.

I thought FrankC was looking into building a CT175 for the 200GP class. And I also thought I was told that it was a valid bike for 200GP. But I may be wrong. Havn't finished my coffee yet this morning.

Craig,
Frank is building one, but told me he was building it was for ULWSV. If they do allow them in 200gp I'll stop racing in the class. I mean jeez, it's 3-4 years out of class, and not close to anything they built prior to that. There are enough bikes in 200gp now that they don't need to bolster the class with exceptions.
And if they really make that kind of power they should eat the MT Hondas that only make about 28hp in uLWSV. In AHRMA they limit them to 30mm carbs...which means you have guys running them with carbs bored out to 32mm at least.
I've invested too much into building a class legal bike, I'd just sell them and buy an RS125. I even converted from a vert frame to a sloper knowing that if I did well on the vert there would be people upset because it's an "exception" bike.

If FrankC told you that then what I heard was pure rumor and conjecture, aka BS.

AHRMA's rules for the 200GP class give alot of advantage to the CT175. The Honda's in that class are limited to 175cc. Plus a heck of a lot of weight to overcome.

I think the AHRMA 200GP class champion for the last couple of years has been on a CT175.

Yep, Scott Clough is riding a CT175, heavily modified engine, just devistates the rest of the field. Not sure how that fits into the AHRMA "performance index" but it seems pretty screwy.
And yet they limit the Honda four stroke twins to about 183cc...which means a practical limit of about 21hp. I think there performance index is more of a "popularity index" if you are liked by the right people you get to run your bike where you want to.
