Our reply: If your TTR230 is 2005 or newer the YamaLink will do the job. We recommend sliding the forks UP in the triple clamps 10mm and then adjust up or down a few millimeters either way for your girlfriend's personal preference.

Our reply: There is no 1:1 ratio of fork & rear change. Five millimeter may be more than you actually need. Raising the forks is not for lowering the front end, per say, it is more to "balance" the geometry. I'd set your sag at 94mm and turn the high-speed compression (the big knob) in clockwise 1/4 turn. Also turn your rebound in 1 or 2 clicks. Simply follow the instructions.
Yes, we do make a YamaLink for the new Yamaha WR450
As you know stock is 5.7 kg/mm and at 210 pounds before gear it is recommended you use a 5.8 kg/mm.
I'd get that 5.8 kg. The YamaLink I'd recommend is the RACE version, NOT the 1.5 inch version:
