A newly-developed catalyst and exhaust system greatly reduces exhaust resistance and improves combustion efficiency. It features a resetting including ignition timing, air-fuel ratio, intake cam angle and the use of high-octane gasoline. Power is improved, with increased torque at low speeds and increased power at high rpm.

Provides front-rear reduction in height of approximately 20mm and a snappy, nimble and elastic ride. It provides improved stability at high speeds and superior control in turning. The optional R-tune suspension kit, which provides stiffer driving, is also available.
