Thoughts of a TT500 victim!

[cloggy]

JC, googled it came up as 81/82 XR I think, was pretty easy to find, but they are rare or non existent in the UK
Brent, I'm having trouble finding out the same info for IT/YZ triples. I can't be sure which models were 38mm. They went from 36 through to 43. I also want to find out the standard YZ/IT gap between top and bottom triples. DR400s are I think longer in the head tube than XTs.
The RMC swingarm is dimensionally the same widths and length as a 175 PE, slightly wider without the rear  wheel adjusters
The shock pivots are further back, better for a DR. I checked back through the suzy forum and sure enough someone else had said the RMC was the best DR fit.
  Oldfart cautioned as to a the pivot housing tube being well distorted. It was, so I returned them. That or get a new pivot tube, but it looked like a money pit.
I'd like the White Bros or similar swingarm. But they couldn't have made many.

JC    if the swing arm was at a good price, hold onto it  I have had new pivot sections added to both of mine at  $100-00 each ( same wall thickness as PE ) . Also when purchasing the swing arm Rm c2 you need the axle plus adjusters.

B****r I've sent it back now. It had the adjusters and we'd worked out a way to make the standard axle work.
I could reorder it.
Thing is I spent a lot of cash a while ago on Falcon 16.5"  4.5" stroke shocks so I'd probably also have reset the shock point along the swing arm. Otherwise it's likely to be too high and the springs too soft. It's about as high as I want it with the steel swingarm.

Yeh I didn't find all those, but the prices are pretty sobering. If they are wide enough at the rear then they should go straight into a DR with a very slight expansion of the pivot holes. Twin shock XT stuff is in la la land. I thought the USA was supposed to be in the grips of recession. What's the world coming to eh?

ohh for DR they made specific swing arms aswell. the DR ones are rare though., i think even Scott Stegar at www.vintagefactory.com hasnt been able to find any DR ones. they made them for 400 and 500 and in 2 types for each i think. straight and banana.


yes since the populartiy of the XT/TT 500's increased with the help of the 500 muster in south australia the prices for parts and bikes have just taken off, but you can still get lucky enough to find a sought after magnesium brake plate on ebay for $1.50 if your in the right place at the right time. the TT/XT 500's have always been pretty popular though. i would at least say in SA there is heaps of yamahas but there is stuff all XL/XR 500's around. perhaps if someone starts a XL/XR 500 club they will start to re-appear.

Is there any difference between 400 or 500 DRs? at least on the swingarm. I thought standard they were the same. I remember a dirtbike article on motocrossing the DR . I've got the second article somewhere. They got the triples reamed out, shoved in RM forks and WB banana swingarm and very expensive shocks. It also got a 420 piston and a race cam and Supertrapp. A while back possibly that same bike turned up on the net.
As a trail bike the DR400 was possibly easier to racerize than any subsequent 4 banger till the Honda 600.
It still weighed close to 300 pounds though!

we should really switch this over and discuss in the suzuki section
