considering an rs 125 roller

For those of you who use an rs 125 in the formula 80 class how long do your slicks tend to last? Also Where do you get them and how much do they cost On average. I will probably be looking for an rs 125 roller pretty soon

 

We used Dunlop C compound for around $270 a set and they lasted all season with kart track racing in between.

 

now I want one for sure!!!!! Any one know where I can a roller. If you guys see one let me know!!!!!!

 

I've been half ass looking for one for quite some time. They don't seem to come available too often, at least not at a price I can talk myself into.

 

I have a buddy

in Alpharetta, about an hour from Rd Atl who has what I believe to be a zero hour 1992 (?) complete roller (body is still pristine white) on display at his house.
I'll run it by him tomorrow, see what he says.

 

I think we used 2 or 3 sets of bridgestones to run the complete SE Formula 80series last season ( plus a couple of races out of our region). From Stickboy at under $300 a pair. Your 145 motor should be a blast in an rs chassis.

 

Sweet let me know

 

The rs is is the same from 92-94 right?

 

one other option: pick up a complete RS125, sell off engine and unneeded parts and throw the mini motor in there. That way, you won't have to look for bodywork, controls, etc. and you might even get some spares as well.


a somewhat related question, as I'm considering a similar project, but from the other direction - I have a 125 chassis and need a mini motor for it. Where to look for engines and which ones to look for?

Thanks!

 

Honda 150R motor seems to be the motor to do, or at least that's the motor I want to put in a RS. I suppose a 2 stroke 85 would work but why go from a 125 to an 85 unless you just happened to have a roller and 85 motor handy.

Looking at eBay there are only 2 150R motors at the moment starting at $895. You might be better off buying a complete 150R at those prices. Or just give me the roller so you don't have to fret over it anymore

 

My post gives me dibs on the roller

 

Really depends on what class you want to run in. For superbike50 I'd use a kx65. For formula80 I'd go with the 150r. Although Caleb kicked some serious but with a cr80 powered rs

 

Bastard!!!!!!!!!!!!!!

 

While that's true, he's also lapped me on a kart track riding a ktm 50. Not sure motor size matters much when he's on the bike. Kid has skills well beyond his years.

 

Yes. Earlier models may have a 3" rear wheel instead of 3.5". Fine for the mini class either way

 

Can you fit a 3.5" wheel in the rear swingarm?

 

my "spare" 125 is a '94 TZ125 - going to be racing a newer RS125 this season. I'm eventually going to do some sort of fuel-injected 250 moto3 conversion with the TZ chassis. At the moment, since there is a decent mini series here in OH, I'm thinking it might be fun to put a smaller engine in there and go play.
