I've had a go with this and it seems quite easy to ride (if you don't use auto downshift). I noticed an issue when revving the bike, it twitched to the left. This is because the engine mounting is marked as "longitudinal". But it should be marked as "transverse". This is because the crankshaft is transverse. I know this can be inconsistent with V-twin engines which are sometimes referred to as transverse when the crankshaft is longitudinal. This inconsistency of terminology is described in the "Motorcycles" section on the Wikipedia page:

In LFS, the setting relates only to the crankshaft, so this bike's engine should be marked as transverse and there should be no lateral twitch when the throttle is blipped.
