Compatible Forks

[Kayla]

I am able to get a set of 1995 YZF 600 forks, but they look slightly different to all the other Thundercat forks that I have seen on the forum. They have a slightly different fork leg where the caliper bolts on. Will they still be OK to do the TRX -YZF swap? Don't want to go spend the hard earned if they are going to be a hassle.

The 1995 YZF600 isn't a Thundercat, it's called the FZR600R over here. They'll fit the TRX yokes, the top yokes are identical and the front wheels, discs and front calipers are the same too. You'll need the mudguard though (YZF750 mudguards are the same )

I already have blue spot calipers, will they fit as well?

Are the FZR cartridge type forks?

Just had a look at the parts fiche

looks like it is a damper rod. So that will not be an improvement over the stock forks

Bugga looks like it's back to looking for the next best option.

The YZF750 fork swap is relatively little work, just swapping the steering stem but you need to get the brakes, clip-ons, mudguard and wheel to keep it simple. Also these are pretty thin on the ground.

In my view the best option is to go the R! for route as while the install is a little difficult parts are easier to come by and most likely cheaper. The end result is probably better too as only later YZF750 forks have rebound and compression adjustment all the R1 forks have them

Lots of information on the swap on the forum just use the search function

A few months ago I swapped to a entire GSXR600 '04 front end. It was really easy, didn't even have to change steering stems. I just pushed the GSXR stem 6 mm higher in the bottom yoke, then bought a set of special bearings from All Ballz racing (The bearing have the right ID's for the GSXR stem and the right ODs for the TRX housings). See drawing at below link for a bit of clarity. TRX front-end is shown in phantom.

Later FZR600R forks are cartridge type forks, basically the same as the Thundercat inside. Blue spots will fit on these forks. The ones in the picture look to have a compression damping adjuster at the bottom of the fork leg, just underneath the caliper mount (although the earlier forks had it cast in it was blanked off). The rebound adjuster is at the top, inside (concentric with) the preload adjuster.

These forks, if you can find them, will fit straight into a TRX with no mods or spacers needed. You will need the mudguard though.

Maybe it's not so bad after all

You will also need the yzf600/fzr600 axle. I have just fitted them to my trx850.

I guess I still have to make up the spacers to use the TRX wheel?

[Ghunter]

No spacers required, you just need the fork legs, guard and axel.

Do you think they are an improvement over the stock forks?

[Ghunter]

I don't know as I haven't ridden the bike yet. I getting it registered this week, I will let you know.

Sorry to dig this thread back up, but just wanted to make sure i'm on the right track...

If wanting to fit Tcat forks, all i need is the forks and spacers and guard??? I can use the trx axle and wheel, and 1 piece bluespots will fit? Oui??

thanks gang.
