Understanding LAMS: New Zealand’s Learner Approved Motorcycle Scheme
In New Zealand, the Learner Approved Motorcycle Scheme (LAMS) is designed to ensure that novice riders develop their skills on machinery that is manageable, predictable, and appropriate for their experience level. Navigating these regulations is essential for any rider on a Class 6L or 6I licence to remain legal and insured on the road.
How is a LAMS Bike Defined?
The core of the LAMS regulation is a two-tier restriction system based on engine capacity and power-to-weight ratios. To be considered LAMS approved, a motorcycle must meet one of the following criteria:
- Under 250cc: Almost all motorcycles with an engine capacity of 250cc or less are automatically approved, with a very small number of high-performance exceptions (primarily older two-stroke race replicas).
- 251cc to 660cc: For mid-capacity bikes, approval is strictly based on a maximum power-to-weight ratio of 150 kilowatts per tonne (150kW/t). Additionally, the engine must not exceed a total capacity of 660cc.
The Power-to-Weight Factor
The 150kW/t limit is the technical "ceiling" that prevents high-performance, lightweight race bikes from being used by learners, even if they have smaller engines. This calculation includes the weight of the motorcycle in full "kerb side" trim (including oils and a full tank of fuel) plus a standard allowance for a rider. This ensures that the bike's acceleration remains within a safe threshold for those still mastering throttle control and emergency braking.
The Official NZTA List
It is important to note that a bike isn't LAMS just because it is 500cc. The NZ Transport Agency (NZTA) maintains a definitive list of approved makes and models. Some bikes, like the Gas Gas EC500F or certain motocross-derived enduros, are excluded despite being under 660cc because their power delivery is deemed too aggressive or their power-to-weight ratio exceeds the legal limit.
Why Choose LAMS?
Modern LAMS bikes are no longer just "beginner bikes." Manufacturers now produce high-quality, learner-legal versions of their most popular platforms, featuring advanced electronics like ABS and traction control. Whether you are looking for a nimble commuter in Auckland, a rugged adventure bike for the Taranaki backroads, or a stylish cruiser for Wellington weekend rides, the LAMS category offers a safe, legal, and high-performance entry point into the world of motorcycling.
