Suzuki letter designations.

[98tls]

had read on another web site S is for 1/2 fairing R for full fairing.

AX? What the?

A = Two stroke - yup.
X = unknown surface. Cool. It'll go anywhere.

Really it's not an AX100, it's an AYM100E

Suzuki seemed to keep to the letter designations for the mainstream models, then hit the Sake for the rest.

For my lump: GSX1100EFG
G Road bike
S 4 stroke
X 4 valve
1100 (except it is 1135)
E Originally to designate alloy wheel model
F Full fairing (S for half fairing)
G Year of manufacture (1986)
