Pete's YZ250F YamaLink suspension lowering

Just want to let you know that I have a couple of rides on my yz 250f and could not be happier with the changes in performance in my bike with the yamalink. I also wanted you to know that I was real appreciative of the service before the sale that you provided in your saturday morning phone call. That kind of service is uncommon these days...especially with online sales. I changed the spring, made adjustments on the front end as per instructions, and find the bike more comfortable to ride and start...not to mention i feel that my riding will quickly improve, as i can already tell a difference in the cornering and high speed bump control. I'll keep yall posted...but thanks again.

Paul's 2006 WR250F lowering link spring rate

Paul owns a 2006 WR250F, weighs 90kg (that's about 200 pounds) and wanted to know about spring rates with and without a YamaLink.

Our reply: Your 2006 WR250F stock rear spring rate is 5.1 kg/mm

BEFORE the YamaLink is installed, RaceTech recommends a 5.5 kg/mm spring rate with the stock suspension to achieve proper sag and the best handling. Too much sag due causes understeering, bottoming and wallowing. You say you're not bottoming: was the bike purchased used and from a heavier rider who put a heavier spring on??

WITH a YamaLink on your bike a 5.8 kg/mm spring is recommended otherwise it will bottom too easily and understeer more.

2002 2003 2004 Yamaha WR250F lowering suspension & sag

Richard writes.... "Good Afternoon. I recently bought a YamaLink for my wr250f and I am going to need to get a heavier spring. I weigh about 212pounds and as you say in the article it is very soft. I find it bottoms out when riding off-road I am more of a leisure rider than high impact. Please could you quote me on a spring for my weight.


Our reply....."Okay, let's figure out the spring rate.

At 212 pounds you are too heavy for the stock WR250F spring to achieve proper sag; the stock spring rate is set for a rider of about 180 pounds. And then of course adding the YamaLink's extra leverage requires a heavier spring.

The stock spring on an 02-04 is 4.8 kg/mm.
At 212 pounds with the STOCK suspension you need a spring rate of 5.4 kg/mm BEFORE the YamaLink.
Now we add the YamaLink and the spring you should use is a 5.8 kg/mm to achieve proper sag.

Yamaha WR250 track lowering

Many tall WR250R and WR250X riders & 'moto racers put the YamaLink on to help with the ripples and breaking bumps on the track. They don't lohttp://www.blogger.com/img/blank.gifwer it via the factory option and they reset sag so that the YamaLink does not give them any lowering.....but they want the extra leverage so the rear rides higher and "floats" through the pavement irregularities.
