  • Maxi Luxe - Maxi with a stock Hi-Torque head and mudflaps.
  • Maxi Luxe II - Hi-torque cylinder and ZA50 (two speed) engine.
  • Maxi N - A rigid frame, with no speedometer. It was cheaper than other models, and dubbed the "Poor man's maxi"

  • Maxi Nostalgia - available 1976 only, a black/gold maxi with decals styled after turn-of-the-centruy puch motorcycle logos. The next year these were replaced with the Newport line.

  • Newport II - Newport featuring a ZA50 (two speed) engine
  • X30/Condor - Comes with a Z50 engine (2 speed manual), full suspended, tube frame and only sold in Europe/Swiss market. Damn rare in the US


The Maxi's engine came in three different horsepower ratings: 1, 1.5, and 2 HP, which correspond to mopeds limited to 20, 25, and 30 m.p.h., respectively. The differences between the 1.5 HP and 2 HP versions are minor, the 1.5 HP version can be altered to effectively become a 2 HP version by derestricting the airbox, exhaust pipe, removing the head gasket, and re-tuning the carb. For detailed information, see the Puch horsepower differences.


Maxis were produced in both E50 (one speed) and ZA50 (two speed) versions. The two versions can be identified by the shape of their gearbox covers; one-speeds have circular gearboxes while two-speeds have rectangular gearboxes. Both types are automatic transmissions, operated by a centrifugal clutch, which engages once the engine reaches sufficient RPMs.

Spark Plug

The spark plug on a Maxi should be gapped between .016 and .020 in (.4 and .5mm). Some spark plugs commonly used on Maxis include:

  • Bosch W8AC
  • Bosch Platinum 4214
  • NGK B6HS
  • Champion L86

Fuel Tank

The Maxi's fuel tank is contained within the moped's frame. It cannot be removed. Fuel tank capacity is .85 gallons.


  • Transmission fluid should be changed every 3600 miles using ATF Type-F fluid, which is specified for both gearboxes.

Oil Capacity:

The E50 holds 5.74 ounces (170cc) of fluid when full
The ZA50 holds 9.5 ounces (280cc) of fluid when full

Maxi Guam Edition

A few versions of the Maxi have popped up in America with VIN plates stating they were made in Guam. These actually have quite a few changes made from the standard USA models. Guam models have Honda-style controls with switches integrated into the lever and throttle housings. Also they came stock with turn signals, including special sidecovers which enclose a small battery. In addition to these changes, the swingarm is Magnum-style, but with closed drop-outs for use with sealed bearing axles, as well as built-in buddy pegs. All-in-all the Guam built Maxis are arguably better quality and more modern than the standard USA models.
