A small liquid-cooled two-stroke custom aimed at young riders, with styling borrowed from the big California: a teardrop tank, two-level seat and indicators with side reflectors. It came with a windscreen, hard side bags and an under-seat compartment as standard. It shared its engine with the 125 trail bikes and is now a rare sight.
