TRX850 Adventure bike build - Page 2

I'd love to elephant man, but very few XTZ750s were sold in Australia, and used parts are even rarer. Theres a number of other twin disc 21inch front end I could use; Triumph tiger, yamaha xtz660, etc. Its just a matter of waiting for something decent to come up on ebay, or at auction etc.

This is great!

I just got a TDM 850 motor and am looking to build a frame similar what you have done with the TRX frame here. Ill be watching closely! Any photos you have will be great inspiration....

Good work.

Oh, what exhaust header is that? Is it the stock TRX?

Homerb · 09-12-2011, 05:27 AM

Hi Notaduc, no that exhaust isn't stock, it was built by the previous owner. The frame is heavily modified too. The stock trx frame looks a lot different.

notaduc · 09-12-2011, 06:24 AM

Yea, I have been studying what I can find on the TRX frame, I dont want to duplicate it, just make something actually more similar to what you have. That TRX project blog is amazing btw...

Well the engine is in the frame, and most of the electrics are connected and working. Most, but not all. Still got to get the indicators to fire up, and connect the brake light switches.
The front end has been a major job. I definitely wanted a low front mudguard ala the XTZ750, but the DR650 forks had no mounting points on the fork legs, none whatsoever. So how to mount the low front guard?
Ended up making some clamps out of 3mm aluminium bar, annealing it to allow for easier bending, and fitting it using 6mm high tensile bolts and nuts. Ended up looking like this. Pretty happy with the result, though a major pain in the arse to fit. Actually took four whole days to make and fit these little buggers.

Next was fitting the 300mm front disc. The front disc needed to be 300mm so I could use the four pot Brembo caliper, except of course no-one makes a 300mm disc that will fit onto my front wheel. I bought a piece of 6mm aluminium plate and cut out a spacer to mount to the wheel which I could bolt the disc to. It also offset the disc by 6mm which helped the caliper clear the spokes.

Homerb · 09-19-2011, 02:30 AM

Then fitted the Brembo caliper. Combined with the bigger disc, I'm hoping for enough braking to not need to fit a twin disc front end.

Homerb · 09-19-2011, 02:32 AM

This is how she looks at the moment. Hoping to get the tank and headlight cowl back from the painters tomorrow, then fit the carbys and polish and fit the pipe.

Nice looking build you've got there. I've got a stock ktm brembo with a 300mm disc on the Dirt Ninja round about 400lbs and it stops fine.

Any plans for luggage?

Homerb · 09-27-2011, 02:08 AM

Well got the electrics sorted, and the exhaust is painted and the new muffler fitted. Carbys are on, brakes fitted and bled,
still waiting for the painting to be done, This week hopefully.

I think youll find this what what it DID look like.

toastmuncher · 10-01-2011, 01:17 PM

Not sure how strong those front caliper bolts are, Id have a look at that.

I sound like a right pessimist, The bike looks great and I would start a job with such a fine bike at the end of it.

Homerb · 10-02-2011, 05:48 PM

Thanks Toastmuncher, which bolts are you referring to? The allen head bolts or the gold coloured hex heads?

Homerb · 10-02-2011, 05:52 PM

Heres how she looks now. Nearly done.
