Yamaha Lowering Question: 2012 YZ125

I weigh around 145 pounds do I still have to install a heavier spring and adjust the sag after installing linkage kit and without adjusting them will I still get the lowering I want?

The 2012 YZ125 stock spring is a 4.7kg. At 145 pounds without gear + YamaLink the ideal spring rate is a 4.9kg to achieve 1.5" lowering at 100mm sag. If you do not want to get a heavier spring we recommend setting sag at 94mm stock is 100mm) which would give you 1.25" lowering (100mm - 94mm = 1/4 inch less) and following our instructions for high speed compression and rebound adjustments. For off-road and trail riding this setup would be very good. For pure MX we'd put on that heavier spring with a 1.5" YamaLink at 145 pounds.

Question: Yamaha Lowering WR250X from Ian

My wife just bought a WR250X. She's tiny... 5 feet tall. 28" inseam. 115lbs without gear. We have the Yamaha low seat coming along with your link. Seat = 20mm down. Factory shock lowering plus the link is 1.75" or 45mm. From what I have read and seen, if you turn the handle bar clamps around you can move the bars closer to the rider and make more space for the forks to come up. Could you please advise how far up we should take the forks?

Hello. Your YamaLink comes with instructions that give you several options for the fork raising. About 99% of riders start at about 12mm and then adjust up or down a few millimeters based on personal preference. It is 18mm maximum that we recommend raising the forks tubes; any more than that and there is a great possibility of wheel vs fender contact. There is no 1:1 ratio of front vs rear lowering because changes to the front effect the Yamaha geometry at a different rate than changes to the rear.
