Jason does awesome work, huh?!!!

nice bike. how did you mount the front brakes? what did you use for a hub?

We used an 86 250R hub and fabricated a mount for the rotor. Brakes are factory YZ125.

Just an update to this thread.

I recently updated some things on this machine to improve the overall feel of it, for me. I decided to raise the subframe to match my 450R quad more closely to ease in transition from one to the other. I also wanted to add bigger radiators and full length shrouds to protect my legs from the bruises i've been getting, coming from smashing into the frame rails while turning.

So, here it is. This info is a repeat from another thread but I figured I would keep it in this one as well.

Upgraded to:
YFZ450 aluminum subframe
YFZ450 rear plastics and seat
CRF450 radiators

What can I say Derrick, I'm speechless

And your plastic working ability???? Amazing...
How do you do that??? Keep that great work up!!!

TORKER.

I just noticed the subframe...you know know, all that alluminum sure does make me think.

have you had any issues with it bending or stress cracks?

Going for a look like the 50th anniversary YFZ.

Also ordered some Galfer wave rotors.

Derrick this picture is way old, do you have something more recent. Perhaps from some different angles?

**Louis Mielke** · 02-19-2010, 09:55 AM

Derrick actually sold this bike.

x2 on the shrouds.id like to know what kind they are.

if you are talking about the yellow ones i bought them from him and they are modded yz 250/450 shrouds the blue ones should be the same

**volfan537240** · 03-04-2010, 05:43 PM

how much modding do you have to do to make them fit?

**bzerk** · 03-16-2010, 02:59 PM

you have to make your radiator brackets match the wholes in the fender and also cut half the fender off diagonally my spelling sucks

**volfan537240** · 03-17-2010, 10:21 PM

one last question about the radiator shrouds lol. what years of the yz 250/450 did these shrouds come on?

**Derrick Adams** · 03-19-2010, 05:41 AM

Those shrouds came from an 06-09 YZ250F/450F. It will be hard to find used yellow ones though. New they were $35 each.

I hate to throw in a question and bring this back from the dead after 5 years, but I didn't notice any frame gusseting on this setup. Can Derrick please let me know if any gussets were added on this? or does the tri z fram not need any? Any help would be appreciated.
