Hey Guys. I'm a 92kg guy recently brought a 2012 YZ450F all standard great bike it feels a bit awkward like the back ends higher than it should be.I used to race as a junior back in NZ got up to national level then in the expert class's as a senior.Lost interest for a while now getting back into riding 6 years down the track it all feels the same (Tad rusty) but better on the new bikes except the rear suspension/rear of bike.Any help & or suggestions if you have any other performance recommendations for the 2012 yz450 would be muchly appreciated.
Our reply: "The stock spring rate is 5.8kg/mm. At 202 pounds and expert ability a 6.0 kg/mm spring is recommended by Race Tech before adding a YamaLink RACE 1 inch.

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.

If you are from Russia and buying a Yamaha lowering link please know we ship the same day your order is placed, and have no control of the YamaLink once it leaves US borders and heads to Mother Country. As of December 15, 2011, Russia is taking a long time to deliver international express. Upwards of a month. All we can do is follow it online with the tracking nuber.
