Our baseline of the Yamaha YXZ1000R was 78 rwhp and 58 ft/lbs of torque. The dyno simulates a rolling road test and puts a load with a correction factor to the vehicles results. This dyno has a load cell that gives you the best and closest real world results.
When testing at our Gilbert, AZ facility, we test on a Mustang All Wheel Drive Dyno. However, unlike the Polaris in doing a start and stop test, this allows us to test in a close 1 to 1 gear which is 4th on the dyno. The manual transmission really puts a new element of driving a SXS to the test. Like a dirt bike, you can bang through the gears once at speed but it requires the clutch pedal to get going or to use when stopping. What really separates this SXS from others like the Polaris is the sequential transmission featuring a multi-plate clutch and flywheel. It is much more linear and revs out higher. The Yamaha is more like a car or a bike on how the horsepower and torque curves come into play. It is really difficult to compare these 2 vehicles though. Coming stock with 112 horsepower, it makes just 2 horsepower more than the latest Polaris RZR 1000 at 110 horsepower. ECU Tuning the Yamaha YXZ1000R is a great way to improve the performance of the 998cc, 3 cylinder engine.
