With a seat height of just 575 mm (22.6 inches), riders will appreciate the secure footing and confidence it offers, while the compact fuel tank holds 1.50 liters (0.40 US gallons) for just the right balance of weight and range. Available in striking color options of orange, white, and black, the M55 not only performs well but also turns heads on the track. **
