Thanks to the nearly perfect synergy between the Genesis 120 engine and Deltabox II chassis, the RS Vector stands out as one of the best cross-country sport sleds in the industry. For 2012, it’s back with a three-piece windshield offering better protection, new aluminum HPG shock absorbers, an Engine Braking Reduction System and Yamaha’s original Electric Power Steering.

Because the Genesis 120 mill is smaller, engineers were able to place it much lower in the chassis, lowering the centre of gravity and improving stability in corners. What surprises me every time I hop onto an RS Vector, is the impression of lightness it conveys compared to the Apex, which is built on the same platform. It’s easier to manoeuvre and more welded to the trail than any other Yamaha product, including the Nytro.

Potent yet smooth
The most recent evolution of the three-cylinder Genesis 120 mill is stunning. Torque output is constant, and it offers unparalleled smoothness and efficiency. The latest camshaft update increases low- and mid-rpm torque, providing instant throttle response – with surgical precision.

The 2012 RS Vector uses a new Engine Braking Reduction System (EBRS). When you release the throttle, the sled runs smoother compared to the old model. The track doesn’t jam up anymore, even when aggressively decelerating. Weight transfers are also more gradual, so it’s easier to enter corners and zip down sharp inclines.

Electric Power Steering
After having tried both the Apex and RS Venture TF equipped with Yamaha’s EPS, I have to admit that I’ve fallen under the spell of this user-friendly system, which dampens kickback in the handlebars without affecting their communicativeness or precision in the slightest.
