They have improved a lot since the 851, but are still more likely to need repairs than most other brands. They also require more maintenance, and valve adjustments are very labour-intensive. Parts can be unbelievably pricey. You are also likely to have to wait for parts more than with other brands. The dealership network is sparser than with other makes. I would NEVER own one as my only bike: One would end up missing too much of the riding season!
