Depends on the work But Sully / AKA Craig might be keen. I will PM his number to you.

Well still waiting on the postman so pulled the forks apart to check them and get ready for the upgrade. All looks really good. Seals seem fine and everything else is in great nick. Almost temped to put the them on the FXR for now. I have a second set of Clamps I could convert with the FXR steerer tube. The offset could be wrong will check that later. NSR is 35mm from memory.

Just did a spring rate calculation on the race tech site and the good news is both front and rear springs appear to be bang on. If the bike weighed in at its normal 127 odd kg they would have been off. Handy site. R6 shock spring is way heaver.

Anyway need to get the emulators in and front forks all dialed.

Don't forget spring rate is only half the battle, valving is the other half... You can have the right spring rate/and sag and then ride it and use sweet fuck all of the stroke due to valving being far too restricted.
Emulators should bring it up too a decent standard... Can you buy em straight off the RT site?

Nice project, are you gonna give hamish the smash when its done?

True. I think you can buy direct. Not much in the pricing at all. Had some good tips from CKT.

Hamish the smash. Well isn't the plan to give everyone the smash? Well see how that pans out.

You can buy Emulators from kss and install them your self no worries. Loads cheaper than fork replacement and tuneable if you know what you're doing. I've made quite a few changes to the ones in Dean's sv over the years.

Yeah will be getting some soon and having a play.

I look forward to getting the smash. Will be good racing when this bike is done, Fishy gets his FXR in his chassis, Andrew dials his chassis in better and Dave gets his hundy sorted. Looking forward to swapping paint, my bike could certainly do with some new paint.

Just had a little measure up with the NSR forks. They are the same offset as an FXR so will go on quite nice. Could be a really good upgrade from standard. They are light stiff and you can get a massive selection of springs for them. I haven't checked the steerer size yet but they might even go straight on with a 5mm spacer in the top. So if you can find some MC21 or 28 forks for cheap they could stiffen your the FXR front quite a bit.

Not sure why no one (as far as I know) has used USD RGV250 forks and clamps. I considered them a while ago before I found some nx4 STUFF and they measure up like they will work without a lot of cocking around.

Simple they weigh 12kg. The NSR forks weigh 7.5 or something close to that. You would still need the emulators and re-spring to make them any good. You might as well run GSXR forks then they would be adjustable. ZXR seam popular and hard to find. Not sure on the weight.

They are heavy. The frame itself is light but the forks are made of concrete. My Dad's R1 forks are lighter. The bike still goes mint though, better than spaghetti FXR forks.

I agree. I bought a NSR front end to put on my FXR, problem was that it turned out to be Honda RS250 NF5 so all of a suddenly became far to good for the old FXR. Felt quite guilty picking them up so cheap, the feeling passed quickly enough though .

RGV usds are cartridge no damper rod. They cheaped out on adjusters on all but SP models.
