Scooter chassis diagrams

25^th October 2014

A while ago I drew some diagrams of the chassis of my scooter since I hadn't seen a good diagram of it anywhere. This is a Honda PS125i, a lot of modern scooters have a similar chassis design.

side on view of scooter with chassis diagram super-imposed — the vacant space under the seat is the storage box. the engine and transmission case have a lot of light things mounted on top of them like the air box, ECU etc.
