Pros and cons
Advantages
Larger tank than the 2021 model
The 11 L tank carries more fuel than the earlier 7.4 L capacity, giving you more fuel aboard between fill-ups.
Ground clearance
The 185 mm ground clearance helps reduce the chance of scraping on bumps and uneven surfaces.
Manageable wet weight
At 147 kg wet, the motorcycle has relatively little mass to handle when maneuvering at low speed.
Things to consider
Taller seat than before
The 815 mm seat is 30 mm higher than the 2026 model’s, which can make it harder for shorter riders to reach the ground.
Reduced power for 2027
Output falls from 15 hp (11 kW) in 2026 to 14 hp (10 kW) in 2027.
