Key specifications
Overview
Introducing the 2008 Beta M4, a standout in the supermoto category that perfectly balances agility and power for the street and dirt alike. Known for its nimble handling and lightweight construction, this motorcycle is a favorite among enthusiasts who crave versatility and performance. The M4 is engineered to be as much at home on twisty backroads as it is on urban streets, making it an ideal choice for riders who want to experience the thrill of two wheels in various environments. With its distinct styling and Beta's reputation for quality, the M4 offers a compelling package for anyone seeking excitement on two wheels. At the heart of the Beta M4 lies a robust 349cc single-cylinder, four-stroke engine that delivers an impressive blend of torque and responsiveness. With a compression ratio of 9.5:1, riders can expect a spirited performance that’s perfectly matched to the bike’s lightweight frame. The engine features a Mikuni BST 33 carburetor for precise fuel delivery, ensuring smooth throttle response and a satisfying ride. Paired with a 6-speed gearbox, the M4 allows for quick acceleration and efficient cruising, whether you’re darting through city traffic or taking on gravel roads. The air-cooled design keeps things simple and effective, contributing to the bike's reliability in diverse riding conditions. The M4 is equipped with a host of features that enhance both performance and rider comfort. Its steel double cradle frame provides excellent stability and strength, while the hydraulic front fork (with a 46mm shaft) and adjustable monoshock rear suspension work together to absorb shocks and maintain control over rough terrain. Stopping power is assured with its single disc brakes, 310mm up front and 220mm at the rear, offering reliable deceleration when you need it most. With a seat height of 870mm, the M4 caters to a wide range of rider sizes, while its generous ground clearance of 305mm allows for confident cornering and off-road excursions. Additional highlights include electric starting for convenience, making the M4 ready to ride at a moment's notice. **
Pros
- Versatile Performance: The M4 excels in both urban and off-road settings, making it a great all-rounder for adventurous riders.
- Lightweight Design: Weighing in at just 133 kg (293 lbs), the bike is easy to maneuver, adding to its fun factor, especially in tight corners.
- Adjustable Suspension: The adjustable rear monoshock allows riders to fine-tune their setup for optimal comfort and handling based on personal preference or riding conditions.
Cons
- Limited Fuel Capacity: With a 10.5-liter fuel tank, riders may find themselves refueling more often on longer trips.
- Single Cylinder: While it provides good torque, some riders may prefer the smoother power delivery of a multi-cylinder engine for highway cruising.
