Rear Suspension ???????

[lightweightstickers]

Can anyone tell me what the purpose of the movement on say a timbersled or m10 or any other company that applies this method does on the back swingarms. A few people have said that its where you adjust your weight transfer. What would happen if that wasn't thier? I would think with the technology we have one could control the weight transfer with progressively valved shocks?

That is the coupling point of the suspension. Meaning, the front and rear arms will move in parallel when the rear arm hits it's lowest travel point.Pretty much all of the factory trail/ crosscountry sleds use this. Yamaha has used this since the introduction of the pro-action chassis (1997). Thier is a good article in one of the mags about this, from a number of years ago.
