History
The Cimatti Gran Prix XL is a red top-tank Italian moped built around the Minarelli V1 engine — the same powerplant that underpins dozens of European and US imports. Cimatti was one of many Italian manufacturers pairing compact tube or pressed frames with Minarelli's reliable 49cc two-stroke and automatic clutch.
Top-tank styling put the fuel tank between the seat and handlebars like a miniature motorcycle rather than a step-through Moby. That look sold well in the US moped boom of the late 1970s when buyers wanted something sportier than a French commuter. The Gran Prix XL name signals the longer tank and XL trim level within Cimatti's lineup.
Surviving examples benefit from the same parts ecosystem as Puch-adjacent Minarelli bikes: Treatland, 1977 Mopeds, and European sellers still stock V1 gaskets, carbs, and cables. Verify engine and frame numbers match — Italian imports often arrived with paperwork gaps that complicate registration today.
Minarelli V1 tuning basics apply: belt tension, clean carb, and a compression test before you chase performance parts. Top-tank weight distribution feels different from step-throughs — expect more front-end load at low speed.

Buying & ownership
When shopping a used Cimatti Gran Prix XL, run a warm compression check against a known-good bike, confirm the engine turns freely, inspect frame rust (seat tube, down tube, dropouts), verify title and VIN match, and take a test ride for clutch grab and idle stability. Budget a carb clean, fresh plug, fuel lines, and final-drive service on any “runs good” listing.
Use the full buying guide checklist before you pay, and confirm legal class in your state via US moped laws.

FAQ
- Is this a moped or a scooter?
- MopedMasters focuses on pedal-capable / classic moped platforms with chain or geared drive — not modern CVT scooters. See moped vs scooter.
- Where do I start if I just bought one?
- Fresh fuel, plug, air filter, chain slack, and a careful first ride. Then work through the maintenance hub before performance parts.
- Can I use the online calculators on this bike?
- Yes for 2-stroke singles — port timing, intake length, pipe layout, and premix all apply. Start at the tools hub.
