NC35 shock replacement

[fastdruid]

Does the NC30 shock fit the NC35?
Are there any other shocks from other bikes that'll fit?
Will the (aprilia) RS250 shock with a NC35 spring work?

I'm after cheapest option atm as I need one for the track bike until I can afford an aftermarket decent one, the existing shock has a big blob of rust on the damper rod so first use it'll tear the seals to pieces and piss oil.

i wouldnt go down the route of the aprillia shock as it was designed to work at a different ratio, look round and get a good original one (one with the remote), i may have one some where. If you set the original shock to 5 mm sag and the adjuster at half turn out ( it only offers adjustment up to the first full turn out and lot of shocks this age the gas will be gone you need to test it first) you wont do to bad with that will be a better option than using something not designed for that ratio of linkage. Obviously its not gona be as good as a aftermarket track job but if you aint got the money its your best option. you will need to offset the hole on the rear linkage by 3mm if using the rvf linkage to get the ride height the designed aftermarket shocks acheive, easy job just weld washes to the side and re drill. The set up for the ohlins shock and the maxton unit is much longer than the existing unit as that is a bit of a fault of the original one is there isnt the travel required.

Good original NC30 you mean (as the NC35 doesn't have remote), I've got an NC30 shock which is why I was wondering if it fits.

Am I better off to use the NC30 or get an NC35 shock rebuilt (I now have two dead ones, one with the rust spot, one with no damping)? The advantage of getting the NC35 shock rebuilt is that the shock would then find itself on the road bike (which has an OK original shock) once we get an aftermarket one.

Trouble is although its an NC35 its got NC30 linkages (triangle and tiebars) with the tiebars/dogbones cut and re-welded to shorten them (as far as I can measure to 103mm centre to centre), no spacers above the shock fitted for ride height. At the moment I've only got a NC30 rear wheel but as the frame came without wheels I don't know what this setup was setup for, 18 or 17inch rears. Any suggestions?

the triangle area described i beleive are all the same on both bikes except the bearings and bushes differ between models, alterations here will upset ratios, the adjusted "double dog bone" linkage needs measuring accuratly center to center ( outer edge to outer edge) i can tell you what that should be, as for the shock fitting there shouldnt be a problem all aftermarket shocks for vfr and rvf are same length with vfr the setup would be a longer aftermarket shock ( 15 to 20mm) a rvf "dogbone linkage" and a 17 "" wheel. Forthe rvf same extended length shock original linkage and 17" wheel if you have 18" wheel it will be to much with that, thing to do is put it together and see ive seen people use 18" wheels as a wet on a 17" setup without to much trouble. I thought it was vfr you originaly had, i would of thought a stock rvf to be a better option than the earlier vfr one but i have no experience with these and couldnt tell you what to adjust that to.

Lol, it's confusing me let alone anyone else!

To clarify (if possible) we've got a road going NC35, pretty much stock. Then bought a NC30 trackbike fitted with an NC35 engine which came complete with most of the NC35 it came from[1]. The idea is to rebuild this 'spare' NC35 pile of bits as a track bike, so far I've fitted the engine into the frame and taken off the swingarm/suspension to grease it up (which is why the questions on it)[3].

Its really going to be a mish mash of NC30/NC35 bits anyway.

[1] Missing wheels, forks (plus front brakes) and bodywork[2].
[2] Although the NC30 bodywork is NC35 style and I'm sure can be made to fit.
[3] Plus bought a load of bits.

Just for future reference then, are aftermarket NC30 and NC35 shocks the same or just same length?

I disagree with Chris on this one. I have the RS250 Aprilia shock and it is brilliant. You would not want to fit it without getting it regassed, oiled and set for your weight but a competent sus shop can sort this for you.

I do not know a single person on here that has fitted this shock and been disappointed with it.

For the money it is a bargain and works very well. It is also taller than std which is nice :D

you do now mate....Fontyyy.

[CMSMJ1]

lol - So did he get it sorted and it does not like him? I want another one for my other NC..lol

Will keep an eye on the for sale section! :D
