Model Notes:

200cc models:
Had front shock absorbers.

200cc models:
Electronic and non-Electronics had same performances.

Innocenti brought in the design house Bertonie to completely re design the GP range. This model was only known as the GP on the UK and a few other markets, on all others it was known as the DL.

On very early GP's, grey tool boxes were used, later switching to back. Other plastic parts used were panel lourves, rear frame grille, fuel filler cap and rear light housing. All these were not painted, but remained in their natural 'plastic' color.

UK models sported chequered flags to go with their 'GP' name, while all other markets wore the ink splat on the front leg shields.
Seat frames and covers were different to all previous models, being shorter and more square in design. The Electronic models gained, again for the UK market only, 'Electronic' sticker to the front leg shields, and a different sloped back seat. All other markets did not get these last two features, keeping the 'normal' GP seat.

First Version until mid-1970:
Horn grill and rear air grill are cast aluminum, metal gas cap.

Last Version to end of production
Horn grill, rear grill and gas cap are plastic.
