The 150 kilo is a bonus, have thought about one of these myself, as that is the maximum weight the rear m/c carrier on my motorhome is certified to carry.
A mate has one and comes along on evening back roads jaunts to a pub or café. Keeps up with everyone on the open bits and loves it when the lanes become narrow, gritty and potholed. I looked at getting one but found the clutch heavy, but then again I have little strength in my left hand and went fully automatic
