Fitting the YZF450 Radiator

Its a lot bigger than the standard one, quite a few members have fitted them in various different ways.
This is how mine is fitted, it requires no modification of the fairings (it clears them internally).

This is the beast, they have over double the core thickness of a standard radiator.

Top fixing bracket, fits to the standard two mounting holes beneath the headstock.

Bottom fixing bracket, fits to the two standard mounting holes on the front of the head.

I got a replacement set of silicone hoses from Roose Motorsports and asked them to leave the ends long, I then cut them to size once the radiator was fitted in the final location.

These are the brackets.

Have fun!

Thanks for the drawings, Bernie! Will be very useful if I decide to use this rad for my project, though currently I'm considering an aftermarket KFX450 rad. By the way, unless I missed something you didn't specify the material thickness for the brackets- 4 mm????

Hi Gerrit,
Well spotted, yes it was 4mm aluminium plate.
Very solid, with about 5 mm clearance either side at the bottom where the fairing narrows.

Iam waiting to see the next bit of progress on your project. I like the rear brake carrier and the idea of dumping the torque arm (as it is very close to my tyre).

Cheers
