What oil is recomended for the trans on the XC line up

Motrex Top Speed (or equivelent) 4T 15W50 full synthetic.

I have a '08 300XCW and that is the recommended oil in the manual listed for the XC/XC-W/EXC...125/200/250/300.

I run Spectro 4T 15W50 full synthetic.

ya, why is it that they have you use a motor oil in there instead of a gear oil? I always thought there were friction addatives that were different between the two.

Good question.

The 4T synthetic is formulated for motorcycles which, in many cases, use the same oil to lube the engine and tranny. Shear-resistant additives are included in this particular lubricant.

Notice it's a multi-viscosity oil as well. Gear oils tend to be straight-weight lubes which can potentially limit their effectiveness with very low external temps.

I'm no expert...I only glean info from technical articles and such.
