Yamaha TRX850 Enthusiasts Forum

I was just wondering if a '00 R6 front end is a good idea as a replacement to the standard for the trixie?
I was going to get the calipers of this front end and was thinking about doing a whole front end replacement anyway. I know a few have gone down the path of fitting the R1 front (which looks awesome BTW). I just thought the R6 front end might be like going down the straigt swap over road ala the thundercat conversion.
What do you reckon, is it a good idea?

if you want to get some new forks, make em half decent USD (up side down) forks for better response, thus 2000 R1.. from memory the R6 didnt go USD till like 02-03.

If you are going to keep the same style of fork, save money and get your current ones resprung / sealed and put some blue spot brakes on.. will make the WORLD of difference for you.

If they are of the cartridge variety then it would be a worthwhile exercise...... Not sure if they go straight on though.

Later, full adjustable Thundercat forks and calipers would be cheaper / easier & give the same results.

Well if job is worth doing it's worth doing well. R1 USD front end here we go.

1st question is whats the best way to drive a speedo with this setup?

Hope you don't mind Quan-Time but I might take you up on the offer of help in this thread too http://trx850.motomaniac.net/forum/viewtopic.php?t=1063

sure thing, we are all friendly around here.. Anything you need im sure someone can help sort you out or point you in the correct direction..

check out http://users.on.net/auska/bike and have a looky at the pics.

Okay. Here are some more questions. Search didn't bring anything up for me so rather than starting another thread.....

I was talking to one of the guys at City Wrecking at Slacks Creek. They have the modified TRX in there, one of the mechanics from Yamaha own's it. Anyway, it has a GSXR750 front end on it, brakes, etc. Are there any advantages over doing an R1 front end. He said the fork almost bolted straight on with only a thin spacer need for the top of the steering stem and the top plate. Do these forks perform? Depending on year model $1500-2000 for the lot. Only issue that I caould see with the setup was lack of clamping area above top plate for clip-ons. Immediate advantages I could see were bigger diameter stanchions and 6 pot calipers.

WAY over priced at $1500 to $2000. R1 front can be done for around $600.00 ish so I don't think GSXR prices should be that much more. Yes they will perform. And look bitchin .

Where can you get an R1 front end for $600 ish ? I couldn't find anything for under $1500

Got my front end for $500 on Evilbay . With great help from loads of good people on this site. Thanks again guy's.

Any front end goes in easily (if you have access to the right tools / people)R1 vs Gixxer forks - very little in the newer ones (but be aware that the 750 has been around for years and has used USD for most, if not all, of them)

Personally, I have a dislike of using non Yamaha parts but each to his own.

For what it's worth, the YZF750 front end goes in as easily as any other and retains the speedo mechanism / drive.

Bear in mind that the cost of the front end is way more than just the forks. You will need new wheels, discs, mudguard and clip ons as a minimum. And then you need to paint the wheels!

I'd say that £400 (1000 of your foreign dollar things) to buy the bits as an absolute minimum - personally I spent more than that on the wheel and discs!

Very true Phuk , but I was told by my local race tech guy that ( now this is his words and he does this for a living ) early R1 much like YZF 750 forks are not that well made and still need work to make a large improvement over srung and valved stock forks , and if your going to that much trouble you should start at a higher spec . I was lucky to get all the parts phuk said and more for that price. P.S. I'm not trying to upset you guy's with yzf and other frontends just passing on what I was told.

I was told omsething similar and so nearly didn't bother but .... I can only speak from experience but the difference the YZF forks made on mine was enormous (and my original forks had been reworked for my weight)

Sounds like you got yourself a bargain!

Another things springs to mind with using Gixxer forks is that you would need new calipers as well

That price range I quoted included the calipers, discs, wheel and master cylinder. I can't remember his name, but he said in his opinion the best handling modified bike he has ridden.

The only issue they had was the clips which they solved by going with a street fighter style setup with handlebar and clamps. You could easily use raised clip-ons which bolt below the top plate if you didn't want handlebars.

I also like the idea of using Yamaha on Yamaha etc. My other planned project when I have the money is a full XR6 drivetrain and mechanicals in a 66 mustang coupe. Some say blasphemy but it has the blue oval on it so I'm cool with it.

I think for the TRX I would probably go the YZF tuned route and save the mix and match for a project bike. One plan is the TDM project I mentioned elsewhere and another idea is to put a VFR750 motor into a 400 chassis or similar or a frame made by myself. All just ideas at this point but I love to tinker and can't stand having standard stuff.

So did my price range. XR6 in a hairdressers coupe sounds like a great idea. When i lived in the U.S I had a '66 hard top Galaxie that I was going to go the Super Roo thing with to show the Ozzy side of things but like yourself had projects lined up in my head ( still do ) and not enough time (still dont ) but thats life, you get that.

What I meant to say was XR6 TURBO. I have done a fair bit of measuring and checking things out. Had a chance to look at a bare coupe shell as well and I am pretty sure I could make it work without too much hassle. Only thing is getting the financial controller to release some funds and to have somewhere to do it where I don't have to pack it up all the time.
