Ricky and Alt, rode my XChallenge for 19000 klm and never needed a sixth gear. The wide spread of the 5 speed and the power and torque characteristics of the motor covered everything from hard off road to highway. If you were to do a lot of highway then a 1 tooth up on the front sprocket was all that was needed.
I would think that the extra power and torque in the Husky would make the 5 speed even more adaptable, will just need to see if they fitted a steel gear shift lever unlike the alloy one on the BMW.
The very existence of flamethrowers proves that sometime, somewhere, someone said to themselves, “You know, I want to set those people over there on fire, but I’m just not close enough to get the job done.”
