2013 Yamaha Lowering: WR250F for Dale

I am anxiously awaiting the Yamalink for my 2013 wr250f. I do have a question on suspension set up. Your site says go with a 10% heavier spring and I am assuming that is for front forks and rear shock? I am going to upgrade valving and springs with RaceTech and was wondering when I use their chart if I should just "up" my weight? I am 190lbs should I use 210lbs for my spring sizes( forks and rear)?. Thanks in advance for your help!

For the 2013 WR250F we recommend a 5.8kg spring for a 190 pound rider without gear. Then reset sag per our instructions. Many find the YamaLink with heavier spring alone makes the front of the WR250F handle tremendously better due to less front wheel weight transfer. You won't be blowing through the travel as easily. I'd set the YamaLink + 5.8kg spring + resetting sag per our instructions BEFORE doing anything to the front.

Lowering Yamaha 426 2001 and 2002

Is the 2001 and 2002 the same? I am not sure of the year of this bike. Thank you.

You can verify the year of bike by the VIN that is stamped on the frame. 10th digit is year. The 2001 and 2002 YamaLink are NOT the same.

Yamaha Lowering Spring Rate: 2003 WR250F

I would be grateful if you can help with setting suspension and sag on my wr250 2003. I am a little under 14 stone and 5 1/2 feet tall.

The stock 2003 WR250F spring is a 4.8kg. At nearly 14 stone you need a spring of 5.6kg to achieve proper sag BEFORE a YamaLink is installed. WITH a YamaLink at 14 stone a spring rate of 5.9 kg or closest is recommended.

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.
