tzx660s TRX bike rebuild

[dixonj]

Hi all, tzx660 is starting his winter rebuild of his trx 878 and has asked me to post on here. So far paul has fitted a JE big bore kit and had zorst big bore headers made and is planning a hoast of mods for his bike which i hope to post on here. Recently he has aquired some R1 2004 usd forks (from me) yzf 750 swing arm, thunderace rear wheel. I called round to see paul today to see how he was getting on.

An R6 rear shock would probably be a follower with the quality of parts going on here..if you are , a small amount of upper reinforcement needs to be removed from the yzf rear to allow the shock resevoir to work freely..and needs to be dropped through from above...also, ive noted a few times that the side arms of the yzf are often a bugger with fouling muffler cans..a good fun set up though...looking to the 878 piston fitting...what thoughts to useing a tdm 900 barrel with the trx head..?i think i have heard someong doing that somewhere..[obv there is the frame lug issue]..

about to chop off the rear end.



to late now



trying the R6 rear end on





Paul has also machined some stainless pistons for the bluespot calipers that will be fitted front and rear

Any idea what year R6 this tailpiece is from?

Tempted to do this mod to mine.

1998/ 2002 5eb model same as the one my bike, will be posting all the pics of the fabrication as it progresses.

[misterdimwiddy]

Thanks.

I will monitor progress, start buying parts and then get the angle grinder out.

Hi.
Doing the same myself this winter - using a carbon 2003 R6 rear end:



I _hate_ welding.....



Will post pics when the project is done

[dixonj]

Small update Paul turned some slugs so as to get a good strong weld on the modded rear end.











hopefully this thread will help other people wanting to do the same rear end conversion

small update, rear all welded up just need to tidy up welds and then its off to be powder coated gloss black along with some other parts

[Con Rod]

very tidy job on the rear subframe and you get to hang on to the luggage hooks. Great way to do it. Keep it coming

[dixonj]

Quick update Paul has got his frame back from the powder coaters and looks like new


















really looking forward to this rebuild

[Tarwetijger]

What are these?

[dixonj]

blue one is a fzr400 race bike and the red/white is another special project Paul is building don't think i can say what it is. I am sure Paul will be on later to comment

[Tarwetijger]
