We already discussed the reason for not going with the single shaft one page earlier. The four gears do look like a lot of extra friction and complexity but it is really just one extra gear contact point compared to the Awesomatix tourer. It's certainly more maintenance than previous designs, but if it works on the track, it will have a following. I'm not so convinced by the sideways stick pack design though. That does seem a step backwards as competitors are getting slimmer and slimmer with great results.
