Oh my god, I've been riding for 24 years if you count the mopeds! I must need therapy:
Fantic Cabillero

BSA Bantam - plunger frame model

BSA C15 SS80

BSA B25 Star Fire

Triumph T140 US Spec - chopped with ape hangers

Honda cb 250 RS

Kawasaki Z400J

Suzuki GS 1000 S - with Yoshi big bore kit, extended swing arm etc.

Triumph Thunderbird - 900 Hinckley triple

Yamaha YZF R6

Yamaha YZF R6 - wrote the first one off

Ducati ST4s
I think there is a pattern emerging amongst the ST riders - moped, crappy BSA 250 single, some jap stuff then an ST?
