PurposeDesigned as a versatile V-twin adventure machine that handles fast tarmac roads, mountain passes, and moderate off-road tracks with equal confidence.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary).
