Pros and cons
Advantages
Adjustable suspension
The Showa fork and shock provide multiple adjustment points for tuning the suspension to the rider and terrain.
High ground clearance
The 333 mm clearance gives the bike room to pass over trail obstacles without the underside sitting close to the ground.
Electric starting
Electric start avoids the need to kick the engine over.
Things to consider
Tall seat
At 958 mm, the seat can make it difficult for shorter riders to reach the ground with their feet.
Chain upkeep
The chain final drive needs periodic cleaning, lubrication, and adjustment.
