Anyone know if a 1984 CR125 rear hub will fit a 1984 CR500?

So my CR500 has what looks like a clear coat of some sort on the pipe. Can someone tell me what it is?

Not much help I know but my suggestion is contact OTZ and ask him if he has what you want. Guys like that have tons of stuff that never gets listed on the website simply because they've got better things to do.

Well I bought the bike guys and at this point I'm thinking 1) Ride it and see what I think 2) I won't know for sure what's in it until I pull it to bits.

If/when I do have it apart I'll put some info up here.

# Fun tracks (You will never please everyone with this one though)

Yeah ain't that the truth. :-)

After nearly 30 years away from the sport.... fun tracks is #1 for me.  And a fun track imo is technical/challenging, not overly dusty, has vintage friendly jumps (ie no idiotic supercross s**t) and is not stoopid fast (surprisingly old bodies break if you smash them into the dirt at high speed). Fast, boring, dusty and dangerous and I'd rather stay home and mow the grass.

We have a winner sleepy, all I gots to do is upgrade my balls :-)

I think 14-56 is standard on the mx 490's. Reason 3rd gear in particular interests me is coz that's the trick to a good start with those bikes. For me at least. A lower 3rd could be a significant drawback, four lap races and all. I was even thinking I'd like to try 14-54 with the close ratio box and a strong motor.

14-51 or 14-49 (can u get a 49??) might make for a big gap with the 3rd to 4th shift on the wide box...

Hmmm interesting. 3rd gear is 10% lower on the GS from those numbers, that seems like a lot. 10% on the final drive is going from 56t to 50t to make them similar if I understand it correctly??

Thanks sleepy. I don't understand tho…stoopid question... if 1,2 & 3 have the same number of teeth why are the ratios different?

Can anyone tell me the difference between the close ratio mx gearbox (RT?) and the wide ratio enduro box (GT?). The ratios for the mx box are easy to find but I can't find any info on the enduro box. Is it an easy job to convert to an mx box? Cheers.

Thanks Geoff, that's really helpful. As you say, pretty expensive when the costs equal the price of the bike!

Ahh remember the good old days when thieving basturds used to have to bash you and steal your wallet. :-)

Hey Geoff, thanks for the info. I'm looking for a nice '81 490 maico. I haven't seen many for sale here and the few I have seem expensive for what you get. Not cheap in the UK either but some very nice bikes.

I'll get on the govt sites and see what I can find. One unlikely thing I read was that once you take all the port fees etc into consideration air freight becomes competitive. Sounds pretty unlikely??

Would you have a rough estimate of the port fees I should budget for on top of gst/freight/duty?

Anyone here have recent experience with buying a bike in the UK and freighting it to Australia? I've seen some very tempting rides but I don't know if its a realistic option to bring one here (Perth). Any and all advice appreciated. Cheers.
