SIP have managed to gain the assistance of a major European producer, VAPE, to manufacture these high-end ignition systems. The materials, production and construction of the SIP Performance ignition systems are of the highest quality.

Due to the eight coils included on the stator plate, enough power is created at even tick-over revs to fully illuminate the lighting. Both AC and DC versions are available and we recommend the DC type if you wish to power digital components such as the SIP Speedometer, or you require a high battery loading charge. By using the DC version with SIP Speedometer you require a Rev Signal Filter from KOSO, or you can also connect the brown cable from the SIP Speedometer to the white CDI cable of the SIP/VAPE CDI with an extra cable.

The CDI module is available as a 'Road' version with a static ignition point, similar to the original item, or a 'Sport' version that includes a variable ignition point, which advances at low revs. This increases the available torque – especially at the lower end – and the ignition point is then gradually retarded as the RPM rises into the power band. The pick-up on the stator plate is split into two and arranged on top of another instead of next to each other as with the original design. This eliminates the possibility of false positioning during the initial set up, due to the sloppy manufacturing tolerances included on many engine casings, crankshafts, stator plates and flywheels. The exact ignition point is clearly marked with a precise line on both the flywheel and stator plate, which allows ignition adjustment without stroboscopic lamp. All you need to do is find out the top dead centre (TDC).

One of the other advances achieved is the production of the inner flywheel unit as a single component, avoiding a riveted boss-mounted cone and uneven rotation. This greatly reduces engine vibration, while also noticeably extending the working life of the flywheel-side crankshaft bearing. The fan itself is CNC machined from solid aluminium and delivers an identical volume of cooling air to the cylinder as the original throughout the whole rev range. SIP claim the amount delivered by most aftermarket ignition systems is easily surpassed with their design, but without preventing higher motor speeds.

The flywheel intended for the DL/GPs weighs 1650gr and for the LI/LIS/SX/TV 1690gr, making them both considerably lighter than their original counterparts. This primarily improves throttle response, but leaves the motor easily manageable in urban traffic and while carrying a pillion.
