Can I put a different bike's front brake disk on?

**pyrocam** · 4th October 2008, 20:27

I have to buy a new front brake rotor from suzuki japan for my project 2001 RGV150 but thats $320+gst or so can I mangle another bikes front disk on there somehow? are there ways to do this?

cheers
edit: already tried freddy's disks, cant be done since its plate shaped. also the model is too weird to supply aftermarket from NZ, singapore, or malaysia. (let alone standard)

should be able to get a metal gear one that will fit, apart from that just hope one of the streetstock racers can help you out.

(botany honda get metal gear discs) i do not know who else does em.)

Take old disc to an engineering workshop. They will turn one down pretty quickly/cheaply. ASK...

by turn one down do you mean fix the existing disc or build a new one. A disc manufacturer (freddy's discs) turned me down because it would be too difficult due to its shape

I asked around at several bike shops. they advised me it was already quite thin and they wouldn't be able to grind it down without going past the required thickness (I dont know what that number is)

the discs are currently 3.73mm OEM is 4.5mm and their runout is .03

NO, turn one down in a lathe... make a NEW one to correct thickness/diameter... Phone a few bike wreckers, or E.mail them. Let the fingers do the walking.

have done, parts for this bike are very rare in NZ only sold here (new) for 2 years.

are you sure an engineering shop can do one if its not flat?
I have been told otherwise, perhaps you can suggest a good one then?

You dont list where YOU are... look in the phone book... phone around...

I am in Auckland but I am not fussed where I get it from. I have mailed or called 5 wreckers in NI, tried 4 bike shops in AK and 2 in singapore and one in malaysia (not sold there apparently)

Its not really answering my question though. you assume I haven't looked into other options, just trust me when I say I have.

If you can find one that fits. It's just a question of physical fit. Often disks are swappable between same manufacturer bikes. Problem is figuring our what would fit, you really need to have the two disks side by side. Prowl along the bikes at Uni armed with a vernier caliper. Would an RG150 fit ? Or a GN250.

Yamahas, there's lots of interchangeability. Suzuki I think is fairly good., Don't knwo about Honda.

Basically , two issues: bolting the disk to the hub (in theory you can drill new holes); and the disk fitting into your existing calipers. If you use the caliper from the donor bike, that latter issue resolves itself, but then you have the problem of mounting the different caliper.

Most bookshops sell a magazine(cant remember the name) that lists the motorcycle wreckers in New Zealand. Buy and sell bikes and cars, and parts too.

Todays engineering shops with modern lathe's and milling machines, can do amazing things that USED to be imposible a few years back. ASK one...

After all is said and done, if you have NO options, why did you ask ... if you dont like the answers... your problem. You do have options, but if you cant be bothered .... pay the $320 + GST ...and smile ...have a nice day.

Thanks Ixion, that pretty much nails it

Just a thought, but did you know that the RG and RGV 150 were made in Thailand for their market? We only got them to fill a hole in ours. Did you try any Thai breakers?

Does your RGV have the rear drum and wire wheels? Like Ixion says I'm sure the wheels/brake combo will be fitted to other bikes. Its just a question of finding out what.

Yeah it is rear drum and spoke. I hear, from suzuki bike shop, that the rg150 and the rgv250 both have completely different brake systems. I will go have a looksee when I get my real bike back from the shop

I didn't get to Thailand no. I thought it was Singapore for a while,Then I went to a couple shops in Malaysia. Was a bit of a hassle trying to find one. I eventually discovered it was Thailand but after the hassle of finding shops in Kuala Lumpar (of the halfdozen I emailed I only got one response) I sorta started looking down a different tack.

Ideally. I can pick up a gn250 front brake system and bung it on and she'll be right.
probably better even

edit: cheers for the help. will see what I can find out

If you give me a part number, I can try my contact in Thailand for you.
Racey.

**birdhandler** · 5th October 2008, 16:14

They have a huge range of parts
Ph 0800 846 2020
Even if you have called take your disc and they can check it against others they have
You may want to the front brake as well so if all else fails you can look at what other options fit
they are in ngaruawahia, 415 hakarimata road (across the river)

Turned out my rear disc came off a GSX 250 as well cost $120.00
Good luck
