2008 front forks
1. Can these be swapped into the '07 and earlier models
2. If so, is there any benefit to the swap? I found a set for dirt cheap. I was wanting to jump on them if they would improve the ride of the bike for street/track use. I have heard of people saying the J shock swap is good. I found one of those, but I am not going to do anything with it until the front end is improved. If the forks are better on the '08 model, then I'll get them.

hm, if the forks work for earlier models and use J shock in the back, that'd be nice!
haven't heard any body trying them. if the price is good, buy it and try it? if it doesn't fit, sell it for more than you paid for.

I figured front forks would mean that I could piece together a 17" front wheel assembly, then move the rear to 17" and run nice and sticky tires.

I did see some on ebay. I'm saving up a little here and there before I commit to purchasing them. I'd love to find a 250R around here to take demensions on to make sure. It is hard to get technical drawings of parts (like the ones to MAKE the items). So I'll have to measure them myself.

I have NEVER seen a 250 on the showroom floor there. They sell out way too quickly.

There should be some at the South Central Rally. Bring a tape measure.

Well I'd also measure the triple tree to see if that is an exact bolt up or not. It sure beats machining the stock triple tree to accept the 37's.
That would be the easiest swap.

I've looked into swapping the new forks onto an older model 250 and the costs generally outweigh the benefits, especially for a street bike. You'll have better forks out of the box (stiffer, static rate IIRC) and a 17" rim up front, but you'll need the entire front end to do the swap. That means fork tubes, upper and lower triple clamps, axel/spacers, rim, fender and so on. Not to say that it can't be done, but it's not the way I would go unless I wrecked my front end and got a deal on a 08+ complete front end.
I still envy the tire choices for the 17"ers though... |

would you happen to know if the triple clamp would be a direct swap?

Don't know for sure but I'd say probably not. Old model has 36mm forks and new model has 37mm so you'd have to shim them at the very least. Not something I'd choose to do on such a vital part of the bike!

I meant a direct swap of the new gen triple clamp/steering stem to the pregen frame.

New gen/old gen same bearings.
Direct swap, but you need everything from the new gen. Forks, wheel, axle etc. You should also do the rear wheel swap, all you have to do for that is change the offset on the brake stay arm and mill the caliper hanger 13mm if I remember the spec right. The rear is EASY, it took about an hour. But you need to cut and weld the brake stay. |
