I know there are other posts and i have read them but this is just to make sure.I picked up a full front end of an RVF the other day.The triple clamps are twisted but the forks wheel and axel are straight.
There are not many wrecked RVFs in NZ.My question is will the JHA triple clamp fit work etc.
Thanks

hey fluffy cat. sorry dont know about the jha kit but i get my zxr forks back from the local machine shop this week and am hoping they will work right. just a question to u do u know the phone number for rp racing up in auckland coz i have been trying to get hold of them for some fairings but have not been able to contact them.

Hey Fluffy Cat - if by the JhA triple you mean part number C10054-00 on their website, the answer is yes, RVF forks will work - below is a copy of an email from JhA asking them that exact question. Respondent's email is sasaki@jha.co.jp if you want to follow-up.

"Dear Sir.

Thank you very much for your inquiry about our product. The upside-down
forks of RVF400 can be installed as it is in the stem set which the parts
number is C10054-00.

If you have more questions, don't hesitate to contact us.

Best Regards,

Me again - For anyone interested, I followed up asking them if rs250 forks would work with the same triples and they basically said they don't know. Their response:

"Dear Sir.

Thank you very much for your inquiry about our product.

We regret to say that we don't have experience that we install RS250 forks
with the stem set and take the bike to dyno and also do the real running
test with the bike which the forks are installed. So, we don't know whether
the problem occur with this combination or not. Therefore we don't know
whether RS250 forks can be installed with the stem set in terms of
performance and also in terms of dimensions, or not.


Best Regards,

Hope that helps.

Thanks Jim for the info,great i will order next week.
fstnsr i think RP has moved to Invercargil no joke!.I bought an HRC loom off him i think last year.Sorry no phone number have you looked at the Tyga stuff just saw some of their fairings at GP trading on an NC30 looked good.

Don't spend big bucks on the Jha set unless you're really in to poo.

Just get the RVF triples straightened and fit an NSR shaft into the triples. hey presto.

We've done numerous conversions for RVF, RS, ZXR, TZR and also RGV triples and forks to fit in the NSR chassis. RGV's are the most awkward, but it's only really a shaft change and a steering stopper reposition.

RS front works the best of course, and will also get you the most poser points. RVF works about as well as stock in my opinion, but obviously looks very trick. I've got ZXR250 on my 300, they're pretty good, but don't compare to the RS on a track-attack. Paul's RGV forks are....Hmmmmm....ok, but we need to have a re-think on the internals. Getting his CBR929 brakes to work with an RS front wheel, and VTR disks was a bit of a challenge, but now the braking performance is too much for the fork set-up.

Matt its ok to straighten the triple clamps?.The lower is out by abit about 4+mm top less but its alloy.
Are the RVF triples made out'a cheese when i measured everything up the forks were straight but the triples had bent!good indents on the lower race to he he wonder how the rider did?.

Matt would it be safe to say that most any triple set would work if it had the same diameters for the upper and lower as the forks your using ?
If this is true many newer Honda's (954-929-RC51) triples would work if you(Tyga) changed the stem ?

Like I said, pretty much anything can be modified to fit one way or another.

Some clamps are very wide, so with the extra diameter of the fork tube over standard, steering angle can be very compromised. OK for racing, but not too convenient on the street.

My 300 has a poxy turning radius, but i don't care. Basically because I've got an F3 rad, so I don't want that crunched.

If the forks don't fit the triples, (ie, you're mixing and matching), then that's not a huge problem either. We've bored out the clamps (up to 1mm OD), and also made bushes to reduce diameters, with no ill effects that you'd notice unless you were battling with Pedrosa for the lead. It's simple engineering and (almost) anything is possible.

Concerning the RVF triples being cheese. It's probably true. A couple of years ago I spent the day at the circuit doing silly action shots and wheelie shots for a Hong Kong bike mag. By the end of the day the front end of the bike had raked out by about 3 degrees!

If you get your triples straightened, it's never a bad idea to crack test them afterwards. You can buy a three stage crack test spray which shows up any damage, or chances are that a good engineering shop will do it for you. You could even have them X-rayed if you really wanted to be sure, but buy then you'd have probably spent enough cash to have bought a brand new RS250 NA5 front end anyway!
