2021 Yamaha Mountain Max LE 154 Base

2021 Yamaha Mountain Max LE 154

Exceptional handling in the deep and steep.

Features may include:

• 794cc 2-Stroke Engine

Electric start comes standard on the Mountain Max 800 LE 154. The two-cylinder 794cc 2-stroke engine features an ECM that electronically controls the fuel and oil injection. The three-stage auxiliary exhaust port power-valves controls the gas flow through a tuned pipe that features a stainless exhaust collector and silencer while the Exhaust Pop Temperature Sensor monitors the system. Spark ignition is generated through a digital CDI with knock control sensors, and the cooling is achieved through a liquid heat exchanger system.

• Tunnel Design

The lightweight tunnel features narrow, tapered running boards to aid in deep snow maneuverability and provide plenty of clearance for its eight tooth extrovert drivers and Power Claw track while the chain-case's 9.4° angle provides a more gradual track approach.

• Large Capacity Fuel Tank

Boasting a capacity of 10.4 usg / 39.4 L, the fuel tank offers extended range for even more adventure.

• Mountain Seat

The lightweight M-TX mountain seat's tall and narrow profile eases rider transitions from side-to-side and improves stand-up ergonomics.

• Premium Fox 1.5 Zero QS3 Front Shocks

The Fox 1.5 Zero QS3, coil spring, high-pressure gas shocks feature a piggyback chamber that delivers reduced fading, exceptional control and three easy ways to adjust the compression damping performance settings, so you can quickly and easily adjust the ride based on the conditions and your riding preference.

• 165" PowerClaw Track

The 154" single-ply PowerClaw track uses 2.6" lugs in a 3.5" pitch configuration. The forward curved, slightly stouter paddles resist folding in heavy powder, providing the lift you need to stay on top. The track's profile provides back-country agility with an optimum balance of light-weight float and maneuverability.

• SRV-M Front Suspension

The sleek SRV-M Front Suspension is ultra compact to reduce unwanted spindle and suspension drag when in deep snow. The narrow stance allows for extreme maneuverability and delivers aggressive lean angles for incredible side-hilling and powder-turn capabilities. The lightweight, forged aluminum spindles join the widely spaced upper and lower control arms which produces a large caster angle for tight side-hilling and ease of steering. The clean, narrow overall stance and elimination of the sway bar also greatly enhance deep snow agility.

• Lightweight, Rigid SRV Chassis

The mountain specific SRV-M chassis combines a load-bearing triangulated structure with lightweight aluminum construction to create a neutrally balanced sled that's centered on the rider. The pyramidal upper frame builds chassis strength without excessive weight, and additional bracing is added to the 'punched' running boards for those who take their ride to the max.
