Hey all,

I was just wondering what a good bias ply race tire for the ex500 is. I know I can do the 17'' conversion, But I am just checking too see whats out there for vias ply tires first. The main reason being, that on of the classes I was to run require running on stock rims for the year the bike was purchsed, secondly, at the moment I have more important things to put my money into rather than a 17'' rim. Unless someone knows of one around for really cheap.

Thanks all,

Brad

There are several tire threads in the forum called "Suspension,Tires & Chassis."

Tires for road, track, both...

man, your class doesn't even allow for updating? That's crap.


You're really not gonna find any 16 inch tires suitable for racing. I did some research for my teammates before they decided it was a million times better to do the 17" conversion. But for those that stick w/ the 16's your options are the Dunlop GT501's, the Pirelli Sport Demon's, Bridgestone BT45's, Metzler Lazertec's or Avon Supervenom's.

The general consensus is that the GT501's or the Supervenom's are probably gonna be your best bet if you absolutely need to stick w/ the 16's.... otherwise, spend the money, get some 17's and wrap em in your favorite tires (mine's the Pirelli Supercorsas)

(contrary to what you may think, you can do it for pretty cheap. I understand one of your classes doesn't allow updating, but if you're racing & don't wanna spend a measily couple of hundred bucks on a 17" conversion, maybe you should join Team Cheap Bastid Racing )

I can run 17's in all my classes but one. The only thing stopping me from the 17's is that this class will be the most fun, and most competitive. But, If i can find a 17'' cheap, I will definatly scoop it up, and maybe swap back and forth through out the weekend. Know anyone with a 17'' rim for cheap?

P.S.- Whats the biggest tire I can get on a 17'' rear rim without any mods?

Swapping back & forth between the 16's and 17's requres swapping swingarms & rear braking systems. It's not something you can do just by changing the rims, they're not interchangable (at least not the rear.) The only practical way that I can see to race on both 16's and 17's in the same weekend is to have two different bikes.

w/ the 17's just about everyone runs a 150/60 rear tire and either a 110/70 or a 120/65 front. most will recommend the 120

Back in the old days (before the 17" thing) we only had the Metzler Tire I forget the name but the compound was Comp K. The best time anybody evre did on that tire was a 1:24... at Loudon. And that was the best 16" tire ever. Compare that with the lasest fenominal time by Jeffy of 1:17:7 on 17" race tires, and you can see where the 16" tire is going to leave you. Seven seconds is like a week behind, they'll be timming you with a Calander.

Well, Since I bought the bike I've wanted to do the 17'' conversion. Like I said, the only thing keeping me from it is the class I can only run 16'' rubber in is the most competitive, and funnest. I thought about it last night, and I'll get better life, better control, better everything from doing the 17'' conversion. Plus, it's only one class I'll have to drop. I can still run sportsman, and GP. I think I will do the conversion, so if anyone has a 17'' front kicking around, let me know.

As for the swapping out rubber for that class, I have no idea where that came from. That's not even feasable. I must have been really tired when I wrote that :-\

So, I can get a 150 tire on a 17'' rear rim with no modifications or anything? Just put it on and go?

Thanks guys,

Brad

yup, you can throw a 150 on there just fine.... it pinches it a little so it's not ideal, but the benefit from getting much better rubber on there outweighs the downside of squeezing the 150 onto the skinny rim..... what is it? a 3.5"?

I think my rear rain is a 160.
