just curious about steering dampers and braided lines aswell, any info on these parts would be great.

I believe the ZZR250 forks will fit right in, though don't quote me on that.

IMO, braided lines are more of a fashion statement, though everyone seems to beklieve the hype about better braking. And a steering damper likewise, unless you're a track loon running daft steering angles. These bikes are very old and staid compared to the modern stuff, and head angles very laid back by todays standards.

i think you mean ZXR dave the ZZR is RWU. to fit the ZXR you need to fit the MC21 stearing stem. and relocate the ign lock.

i have a zxr250 usd front end on my 21
you need top and bottom yolks from the zxr
its quite simple really you get stem pressed out of the nsr yolks and pressed into the zxr ones
the zxr spindle fits straight to the nsr wheel aswell (had to get about 1.5mm machined from one of the nsr wheel spacers)
then you need to sort the calipers
i fitted 4 pot brembos on mine with rvf 400 discs just got a couple of adaptor brackets made to carry the calipers
as for the ignition i fitted that were the helmet lock used to be
probaly sounds more complicated than it is

Hmm, not sure I'd entirely agree with that one Dave. Sure, on a new bike, the stock hoses are rather good, but a 14 year old MC21 could certainly (or more than likely) benefit from replacing the rubber hoses - and what better to do it with than a set of "our" (i.e. NSR-WORLD.COM!!) stainless steel hoses?!! ;)

This has been, yet again, another shameless plug by NSR-WORLD.COM!

Well, every motorcycle mag ever whines on about how the braided hoses transform things, and that old rubber is rubbish. Can you imagine the freebies continuing to flow if they wrote 'yeah they look good, but don't make any difference...'

However, have you - or anyone else for that matter - ever felt a rubber hose bulge under pressure? I'll bet money you haven't. If they really were a danger, then they'd be date stamped and the MOT would fail them...

I replaced the hoses on my FJ at 18 years and 85000 miles old as I bought into BS, and nothing improved.

30-15, back to you! Wink

Yeah, of course things improved... my Poser score went up 3 points!!

I'm not necessarily saying I can notice the difference, but then again I can't really notice the difference between a 59hp MC21 and a 63hp MC21... but there are those out there that can though!

If I was to replace a set of hoses on my NSR because the old ones were tatty or I was unsure of their condition (i.e. they were a bit perished around the joints) then I'd much rather spend the few quid extra on good quality SS hoses that should last the rest of the bike's life, look good, and perform at least as well stock, than fork out the cash for the extravagantly priced Honda rubber ones!

Is that 30 all? :D

I have Dave. Take a set of veneer calipers to your rubber hose and measure. Then squeeze the brake lever all the way and measure.
You be the judge from the measurements you get.

Where are these so called NSR-WORLD.COM SS braided lines?
Link please - I did search the site, but could not find them.

Cheers.

Andy, I'm with you for replacement of old tatty lines 100%. But too often I hear of people changing them purely for herd mentality reasons. I still cling desperately to my argument that if time was that bad for them, then they would be lifed and changed accordingly. Maybe I'm too indoctrinated with aircraft parts, which all have a life...

the 350ypvs haynes manual recomend that caliper seals be replaced every two years. and brake hoses every four, irrespective of their apparent condition. don't trust the MOT to tell you whats safe or not. the minimum standard for a lot of brake tests are a joke. brake pad thickness must be less than 1.5mm before you can fail it, and that on a car Shocked brake fluid can be as black as you like as long as the levels ok.
i do agree with dave that a lot of stuff fitted to modern blkes is only to get the punter to buy it and of no benefit at all to the road rider. radial calipers anybody Wink
