The M4 is a small urban supermoto from Betamotor, powered by a 349 cc four-stroke engine of 21 kW. Beta lists it with the Urban 125 and 200 as a city bike, distinct from the larger RR enduro and motard models.

History of the Beta M4
A city bike from an off-road firm
Beta’s reputation rests on trials and enduro motorcycles, but the company has also built road and city machines since the 1950s, and in the late 1990s it entered the scooter market with the Ark. The M4 belongs to that urban side of the range.
The Urban group
In its model list Beta groups the M4 with the Urban 125 and Urban 200, describing these as supermotard-like vehicles suited to the city, with a low seat and great manoeuvrability. The M4 is the largest of the group, with a 349 cc four-stroke engine that produces 21 kW.
Beside the RR Motard
The M4 is not the only supermoto-style machine in the range: Beta has sold Motard versions of the RR since 2006, and since 2018 it has offered a 50 to 125 cc supermoto called the RR Track. The M4 sits between those road-legal off-road derived bikes and the small-capacity Urban models, aimed at riders who want the style without a competition chassis.
Design and features
- 349 cc four-stroke: the largest engine in Beta’s Urban group.
- 21 kW: modest output for a road bike, in keeping with its city role.
- Supermotard layout: the style Beta also applies to its RR Motard and RR Track models.
- Urban positioning: low seat and manoeuvrability, as described for the Urban range.
Beta M4 versions
- M4 4T: the 349 cc model described in Beta’s model list.
- Urban 125 and Urban 200: the smaller models of the same group, including Special versions.
The M4 shares its supermoto style with the Beta RR Motard, and sits beside the trail Beta Alp and the scooter Beta Ark. More machines are in the Beta collection.
