1982 250WR...for vintage motocross?

Greetings;

I have just sold my '82 125 WR...it was a neat little bike, but we have finally gotten vintage mx going in my area and it just wasn't suited for that. And at 185 lbs., I think I was a bit much for it to move around as well!

So...how would an '82 250WR work for mx? Is the gearing so low that it would be more angst for me? Suspension? Would a different pipe help out? Other mods that might help out?

I'm just an Intermediate class rider, if that makes a difference. Thanks.

I can pull a hare scrambles, dead engine start, holeshot on my '82 250WR. Done live engine starts for grass track moto at Qualifier type events and been right there 1st or 2nd gear. That lever on the left, helps you lay down the power. I haven't done any "real" vintage MX with it, but wouldn't be afraid. It would be nice to pass MX guys, on a bike with lights and a plate.

My 84 250wr has cr porting, air cooled. I figure to try the 13t front sprocket with a 55t rear sprocket first. I have a 14t front sprocket to play with too. You can go with the 14t sprocket and go to a smaller rear tire. It's a trade off till you find what works for you. Maybe a 15t sprocket with a 120/80 tire.

Do you race NETRA here in the northeast?

Only the occasional AHRMA race. I hope to do more next year. NETRA is a little too far east for me.

I'm new to this do they race AHRMA in the northeast? Is that GNCC?

AHRMA is a national vintage motorcycle racing club, road racing, trials, MX, cross country, trials and dirt track.

As for your 250WR, it will work just fine. Gear the bike so you can easily do a MX start in 2nd, you will rarely use 1st, and since you have a 6 speed transmission you will also rarely run out of top end, most of the time you will only use 2nd, 3rd, 4th and sometimes 5th.

I have used my 78 390WR for motocross a few years ago. 2nd gear starts are fine as Kartwheel said. I have never got into 6th as that would be 60mph plus.
Run with it as it is to start with. Once you get a feel for what the gearing needs then change the sprockets.
Just go out there and have some fun. I don't win, but my chops ache with the grin ! (wow ... that rhymes !)

12/56 is the secret.....

Thanks for the info.

Okay...it sounds like it might be fast enough for me. Regarding the suspension: I'm assuming shocks AND forks are slightly shorter than its CR brethren, hence less travel?

Yes, both are 10.6" travel, but the rear just has an internal spacer, if you remove the spacer the shock becomes the same length as a CR/XC. The CR/XC length shock on the WR swing arm gives you 11" of travel.

Thanks! What about the forks...a longer/shorter spacer there as well?

The WR suspension is absolutely fine for vintage motocross. Unless you are super fast and expect to win every race the WR will be perfectly fine. I race mine almost exclusively in VMX ..lights and all! Certainly don't feature near the front I must admit however......

The forks have a shorter damper rod. I also race an '82 430WR, totally stock with the lights and all, the only mod is I have removed the spacer from the rear shocks. This not only gets you a bit more travel, but more importantly it raises the rear end and improves turning significantly.

I get knocked down in the first turn, but otherwise the WR does pretty good in MX.

That ride was awesome that's you brought back memories.

Where do they race vintage motocross?

I live in the Atlanta area. That was at Diamond Don's National in Jefferson Texas, but I race all over the country.
