Looking for a complete Suzuki GN125 gearbox.

Paging Warwick

Used to be a minimum 100kmh on the MHR before even thinking about top and that was after I lowered the gearing

from memory the GN is closer ratios than the DR etc

You'd need to check the specs but pretty sure DR200 drops in too, they may be closest.

There is the farm versions and the SP versions and numerious 4 wheelers as well.
They llikely changed a few ratios over the years too in the models
But this is what i found on a 5 minute google.
Nothing that flash, a Cb100 has far better ratios

I am using a GN125 clutch assembly, so was thinking the GN box might be worth a look.

Not if its only 5gears

Well Warwick's mighty GN does have a 6 speed in it - but I'm actually confused as to what model it came from. I did think the 200 had a 6 speed...

What box is that you've broken Tezee ? You may be better off looking at an RG150 or FXR box.

I was thinking the same.

I am in need of a speedo and rpm cables for a rg50. Both of mine are broke and I've been told that the ends can't be repaired....
No, not for a bucket, but a super cool commuter

The DR/DF 125 has a 6spd and will swap into a GN case, I dont think there is much in common between the GP and GN though, will have a look in the boxes of bits tomorrow

In fairness Tzs bike doen't have much in common with a GP125 now either.

Yes I try and keep up with that thread!
If needed I have a GN gearset, however looking at it I think the GP would be stronger as the GN gears were not increased in width over the 6sp versions of that family, the centre spacing looks pretty close, maybe the same (dropped the GP set into some GN cases). The Gn shafts are 10mm or so longer than the GP ones.

I would be keen to buy the 5 speed GN set to look at if its available and a 6 speed set if anyone has one. PM me a price.

looking for a set of Yamaha RD 400 35m for for my Anderson frame YZ125 pre 82

looking for a set of Yamaha RD 400 35m for for my Anderson frame YZ125 pre 82

last time i looked there was a set of rebuilt FZR250 3ln forks on trademe pretty much the same only 36mm and made for slightly biggger twin disks.

They only lack the separate axel cap.
The 35mm forks were used on the E model 250 and 400 (footpegs over exhausts) and F (IE daytona special)
They were likely used on xs400's 650's etc and other bikes of the same time period.
edit
RZ-350 L/N/NC/NCII (84-85)
XS-400 J/K “Maxim” (82-83)
SR-500 E/F/G/H (78-81)
XS-500 C/D/E (76-78)
XJ-550 RH/RJ/RK “Seca” (81-83)
XZ-550 RJ/RK “Vision” (82-83)
XS-650 D/E/F/2F (77-79)
XS-650 SE/SF/SG/SH/SJ (78-82)
TX-750/A (73-74)
XS-750 D (77)

pretty sure the RDLC had them as well.

[Grumph]

Out of that list, the SR500 is probably the most common - and pre 82 legal.
