You can get off centre Mota Litas as well. I had one on my +4. That gives more thigh room.
I agree the seats on the Roadster are difficult to move.
That’s what I have. Works well, but can feel a bit weird when negotiating hairpins as the wheel is eccentric.
Also found that originally, I could not get my seats to slide all the way back, as the runners were gone bananas due to the fulcrum effect of a protruding bolt head under the runners. Removing seats and sinking a shallow blind hole into the floorboards, cured the problem.
