Successful front end replacements have been made using TTR225 36mm fork assemblies but require boring the triple trees clamps from 33mm to 36mm. I have one of these projects in the works using TTR forks, brakes, brake line & speedo drive cable. Supposedly engineering evaluation by others indicates that the 36mm fork tubes will buckle before the bored 36mm clamps fracture implying this is a safe modification.
My second TW has 34mm forks from a Yamaha Tri-Z but required custom fabrication to mount a disk brake for the TW wheel assembly.
The added suspension travel & ground clearance are very welcome improvements.
