Liquid-cooled oil cooler maintains stable 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 coil is built into the spark plug caps).

• reduces weight & complexity

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

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

Diamond-type, high tensile steel backbone type frame.

• optimized rigidity balance for light, agile handling & excellent stability
• engine is a stressed member of the chassis, allowing a lighter, more compact main frame
• compact wheelbase & light weight chassis design provide a responsive & engaging ride

Upright, comfortable riding position is a key feature of the XSR700.
