Quick action throttle wheel to suit GP and Sx type head sets using GP and late Sx handlebar rods with a 5mm roll pin.

Increased in size to reduce throttle roll on opening carbs up.

Made from steel to increase weight in the headset to reduce vibration.

Another Mark Broadhurst designed product to improve Lambretta riding.

NOTE; The headset casting for the throttle stop needs filing slightly for these to fit.
