For Sale / KDX 250
« on: July 14, 2018, 08:53:32 PM »
85 KDX 250, last of the air cooled.
'Harrow ready'

Originally built as a rider to keep, I would call it respectable and functional but its not cosmetically immaculate.

It had a full rebuild a few years ago, new rod kit, mains, Wiseco piston, replated cylinder, DID X ring chain and all the usual swingarm/wheel bearings etc.

I have only ridden it once or twice a year since due to illness or VERi committee duties at events.

It performs well, the motors I consider brilliant as it has torque down low like a tractor and still revs out cleanly.

GMC chamber and muffler


Down sides;

The tank had been painted when I got it and it looked good but it has deteriorated over time and when washing it after the Beaufort Vinduro the paint came off from the pressure washer. I had been expecting it to not look so flash under the paint and had already bought another tank for it that looks a lot better, its pictured next to the bike. Just haven't fitted it yet.

The front and rear rims are different profiles so I acquired another rear wheel for it to match the front rim, its pictured next to the bike, haven't gotten around to fitting it yet either.

Its still on the same tyres as when I rebuilt it, they have lost the edge a bit but I can throw in some new tyres with it, they are pictured next to the bike.

Brake shoes are still usable but probably the only thing needing updating.

I painted the GMC chamber with a clear coat and put it through some heat cycles but apparently not enough as my first ride with it at Beaufort had some dirt stick to the header section as the paint was still soft, haven’t had time to detail it since. basically needs a sand back and redoing

Has the usual paint rub marks from being ridden.
Asking $3000 for it with the spares as mentioned.

Its ready to ride, currently has club rego however its not transferable.

Keep in mind that  the word "Alloy" is a term that means a mixture of elements, we all commonly refer to Aluminium alloy as 'alloy' so dont confuse it with titanium alloy which is also mixed with other elements for best effect.

Coating the alluminium would make sense

According to the moms Titanium is illegal for axles, not sure about other items

I think it would be a fail, the alloy would be too soft and the surface would peel and tear away. Not just wear quickly but rip itself to shreds quickly

Any heat treatable alloy would lose its temper from the braking heat
5083 has a close grain structure and might be the best bet but I think if there was anything in it the Formula One guys would have been onto it already.

I think Titanium might be a better option that alloy but again if F1 don't use it there must be a reason

12 months ago I lost my greatest salesman...

"send it to Geoff Morris?
Rossco (aka GMC Business Development Manager   )

"how good a job do you want?  Rider - just bog and paint - any better - send it to Geoff for a top job in fixing."

And I know he always thought fondly of me!

"I have said before, and do not hesitate in repeating myself - but I don't like Geoff!!!"

"always said he was an a---hole - and he continues to prove it  "

He always had great advice for me too...
"and Geoff "bite your bum""

Still sorely missed

250 & 400 twinshocks look similar and they are both relatively rare

If its a twinshock then it should look like this;

Excellent course, lots of good technical sections with breathers in between.
I found the pines were no problem at all, I think the trick to riding slippery pines is to turn up late, start even later and then ride them after everyone else has cleared the course for you.
One lap was enough for me, I tips my hat to all those that went out twice.

Thanks to all those that made this event happen

Ahhh, your not looking at the forks for ID so they must be aftermarket, I still think you should concentrate on the backing plates.
Some Yamahas have the lug in line with the fork and some are at an angle, more to the rear of the fork tube, that should whittle the suspects down a bit

While I agree with Hoony I did have a KX 250 that melted a piston twice in 2 years (Curse you Sea Lake)
A flush out and new piston and it was fine for several years.

You been a bit quiet of late, are your projects ramping up again now?
