Yamaha MT-07

The MT-07 offers big time fun, affordability and riding enjoyment. This versatile naked roadster offers deep engine torque from its 689 cc parallel twin and a comfortable upright riding position combined with a lightweight, easy-to-handle sport chassis. The perfect machine for both new and experienced riders alike who are looking for outstanding value in a mid-class sport bike.

STYLING

The MT-07 was restyled in 2018 to more closely resemble its bigger MT siblings. The Ice Fluo (pictured), Tech Black and Yamaha Racing Blue colour options are the perfect complement to the MT-07’s minimal, naked design.

- utilizes a powerful 32-bit processor for fast control of the injection & ignition processes

Airbox design features dual intakes.
- design reduces intake noise
- viscous paper type air filter is utilized

Compact, 6-speed transmission.
- Tri-axis design “stacks” input/output shafts to centralize mass
- overall engine size is shorter front to back allowing the engineers the freedom to place the engine in the frame for optimum front to rear weight balance
- transmission ratios are designed to suit the character (torque & power) of the engine
- specially chosen gear ratios means fewer gear changes
- 6th gear is an over drive gear reducing engine rpms at highway speeds for a comfortable ride

Compact, clutch design with light clutch lever pull.

Lightweight, vertical flow flat radiator with ring type cooling fan.
- ring type cooling fan pulls more air than a conventional non-ring type design
- left & right rad covers add a stylish highlight

Liquid-cooled oil cooler.
- maintains consistent lubricant temperatures for extended engine life

Convenient spin-on type oil filter & easy access drain plug.
- for fast, easy oil changes

Convenient oil level sight glass.

Maintenance-free transistor controlled ignition (TCI).
- produces a strong spark for fast starts
- provides precise ignition timing / mapping for optimum engine performance at all rpms

High performance direct ignition coils (ignition coils are built into the spark plug caps).
- reduces weight & complexity

AC Magneto produces 410 watts of power @ 5,000rpm.

Stylish, compact, low mounted, 2 into 1 exhaust system.
- triple expansion muffler design with 3-way honeycomb catalyzer reduces exhaust emissions
- low mounted design centralizes mass for excellent handling & a light weight feeling

Air Injection System (AIS… not ram air) injects fresh air into exhaust ports to fully burn any unburnt fuel, further reducing exhaust emissions.

CHASSIS

Diamond-type, high tensile steel frame.
- optimized rigidity balance for light, agile handling & excellent stability
