ZXR250 - tyres, sprockets, screws/nuts/bolts

**justsomeguy** · 27th October 2005, 22:54

Hi there,

I'll very shortly be needing to replace the tyres on my ZXR 250.

From doing a bit of searching I found the following three names get repeated:

1. Pirelli mtro1
2. Pirelli Sport Demons
3. Dunlop GPR80's

I used to have a set of Sport Demons on my old bike and they were quite good. How much better are the other two tyres??

What would you all recommend for the bike?? I need the tyres to do a bit of everything - commuting, twisty roads and track days.

.... however the tyres ability to provide good grip in the wet and dry is my most important deciding factor.

I also need a set of nuts, bolts and screws for my fairings, I'm missing most of them and the ones I have are rusted. Where in Auckland do you'll recommend??

Preferably central or east Auckland.

I will also need a set of sprockets and a new chain sometime soon - have any of you tried some lighter alloy sprockets?? How much do they cost?? Do they make much of a difference over the standard set?? Are there any light weight chains available too??

I remember carrying the used chain and sprockets from my old 250 and the things were really heavy.... something lighter would be great.

Cheers for any advice.

JSG

go to repco or there is a good engerining out fit on beaumont st down the bottom end cant rember the name of the place, all you need to know is the width and length of ya bolts get em in stainless...

Holdfast in Mt Wellington has quite a few bolts and general crap like that for my bike. Fairing screws, exhaust bolts - you name it they have it. I'm on the lookout for a new fairing hex bolt as well, keep forgetting to ask if they have them.

Mt Eden bikes also has loads of fairing bolts of varying length and colours too. I bought some for a GSXR250 I rebuilt, that had no bolts at all. Can't remember how much they were, but he has heaps..

As for the tyres, I have no personal opinion on any, cos I haven't used any of them before. Best bet I think, would be to go to a couple of shops like Motohaus, Cycletreads etc, tell them what riding you do, and ask for the best tyre, and the best priced tyre. Shop around a bit if you want the best deal, then decide based on how much you want to spend, and which tyre pops up the most etc.. then go with that. At the end of the day, you aren't going to know if you got the best or the worst, unless you spend a week riding each tyre. Everyone has their own prefs when it comes to things like this too, based on things they've experianced and things heard. So you'll never get a straight definative answer

bump(oh yeh tehn charectehrs)

bridgestones mate. i run BT45 and BT92, pretty much just different grade of race tread... the 92 being more race like i believe... never slipped on when riding cept for once under heavy braking from 140kmh into a corner when it went from dry-wet-slippery, but it happened to the 3 people behind me too...

on the other hand, lets go easily when you force it (if you know what i mean)

nuts and bolts... try mt eden - they can order the stuff in for you, then you can go get them anodised (sp) any colour you like.

chain and sprockets - tensile strength is the word... lasts longer. I have a DID gold o-ring chain and its still in good condition after 12k, as for the sprockets, never changed em so wouldnt know...

Whatever you say Young Hitcher

An expert in the subject told me to try and get a Dunlop GPR70 front and a GPR80 rear. So if I can get those - then that'd be first choice.

I already rang Mt Eden and they suggested I ring the shark at Crummer Rd... got ripped off real bad there before - so for my info - how much should a set of nuts and bolts for a fairing cost?? Ball park figures are good enough.

Anybody else - know where and how much $$$ a pair of light alloy sprockets and chain cost??

Hahahaha - I'm the worlds slowest Indian - how can I go racing.

You know a place I can get some light weight sprockets??

Will start phoning around tomorrow.

Those Demons lasted 6k - so I dunno how long these gonna last.

Must try and get down to Cheenic Dwive more often.

Been told I can only get a 140/70/18 in a Pirelli Sport demon. $320 a set

Anyone know if a 140/70/18 rear tyre will simply bolt on to a ZXR250 without any rubbing or tweaking??

How will it effect the handling??

My next choice up are GPR80's for $410

GPR70's are out of the question due to their price... $239 for the front alone

Who is the Dunlop distributor in Auckland??

Anyone know who the cheapest source of a set of 110/70/17 and 140/60/18 Dunlop GPR80'S is??

Hi matey,

BOTANY HONDA are the bizzo - they've bet another big name place by nearly 100

Dunlop GPR-70's are going on along with a heavy-duty chain and sprocket set tomorrow morning.

without putting them all on the same bike and running them through the same conditions, any opinion would only be speculation...

**dveus** · 3rd November 2005, 12:44

Might be worth trying a set of Avons at some stage, they seem to do OK on the gsx. Only really had a couple of times where lack of grip has been an issue, and I m sure not too many tyres will stick so well if there not actually on the ground.
