Suitable rubber - GT125 (18" rims)

**davebullet** · 17th July 2012, 13:45

Ok guys....

OEM fitment on the alloy rims are
Front 2.75 x 18 (80/90/18)
and
Rear 3.00 x 18 (90/90/18)

AJ (is he still bucketing?) was running this Thai stuff called "vee rubber". I don't think the venerable BT39SS comes in an appropriate 18" size.

Are any of you mad enough to run 18" rims and those that are, what rubber do you recommend in an 18"? (apart from black round stuff)

Buy a new frame, put 17's on it... And get some slicks... Won't even be that much more than buying new 18" rubber and much better...

Promise

That's the long term plan. Short term is just to take it out as is and have some fun.

It's not legal anyway with dual 24mm carbs (presume I can just pay for the day and have a play). I have no delusions of actually riding well. I just want to stay upright, have fun and not collect anyone in the process :-) (that should all make you a bit worried).

Basically - have a go and if the bug bites and time allows, get more mechanically skilled and work up a nice little machine.

Cheers... maybe I'm miss-reading things:

I thought the
B/STONE R 100/90 18 B39R SSTL
would be for an equivalent 3.25 or 3.50 rim (not 3.00)

I'm guessing the
B/STONE R 250 18 BT39SS
would be ok for my 2.75 front?

Iv'e used Bridgestone BT45 successfully, get a front for the back as well, just run it backwards.

I took one look at the bike I scored from AJ, took the motor out and filed the rest in the, "do not even think about riding this" corner of the shed. The tyres on it might be OK, you can have the wheels and tyres for a box of Heineken.

Set of 17" rims right here http://www.trademe.co.nz/motors/moto...-492803057.htm

The BT39 do come in these tyre sizes and are the best option you can buy. My daughter is racing a GP100 and they are the tyres I'll be fitting.

Thanks for the offer Drew, but if they are 18" rims I will pass. Next step for me would be as said above (new frame / rolling chassis with 17" rims).

Hmmm, my mechanical skills are limited and I wouldn't know where to start when it comes to fork spacing, rear swingarm clearance, callipers / disk replacement etc.... I might be better off with a rolling chassis and motor transplant

The best plan, but measuring wheel spacers is much easier than fabricating engine mounts to fit an aluminium frame.

just get some shin skins or what ever there called

Don't pass, If AJ put tyres on it they will very likely be much newer and better than what's on there; that'll help you get started.

Great idea, also more engineering than most would credit in that undertaking too.

Just get started on what you have, no-one will care if you show up with the standard carbs to begin with.

Unless your name is Drew..........
