Malossi Team II Inner Rotor Ignition for Aprilia / Piaggio 50cc 2T Air Cooled Models
If you have removed or held a factory flywheel in your hands before, you’d know how heavy they are. Each time the throttle is applied, the crankshaft has to forcibly spin up the weight of this giant engine anchor which is hanging directly off its side. Inner rotor ignitions essentially work in the reverse, having a super light flywheel built into a the inside of the stator rather than rotating around the outside – keeping the heavy part of the system un-driven, and the driven part of the system as close to the centre of the crank as possible to reduce the effect of centrifugal force. This allows the engine to far more rapidly rev, as the flywheel is providing far less resistance to the engine changing rapidly in RPM. A must have for any race setup!
Please note that this inner rotor ignition only provides power to the engine, not the battery or scooter lighting. The factory stator provides direct power to the headlight and tail light, as well as charge to the battery which runs the rest of the electrical systems on the bike.
If you’re planning to use this inner rotor ignition on a road registered bike you will need to run power from the battery to the headlight and tail light, with an inline switch to allow you to turn them on and off when required. The rest of the lighting and electrical systems on the bike run directly from the battery (starter motor, indicators, brake light, ect) and do not require any additional wiring. We recommend upgrading the headlight bulbs and tail light bulb to LED bulbs, which are far more energy efficient. As the inner rotor does not supply any 12V charge to the battery, you will also need to periodically charge your battery. We recommend upgrading the size of the battery slightly if possible. There are many affordable battery charger options available, which include a plug with eyelets that can be permanently installed on the battery so charging after rides is as simple as plugging a single plug in.
Manages multiple maps simultaneously without having to resort to a hand-held device, with just a simple click. Ability to shift the selected map by moving the OFFSET (± 2°).
The inner rotor ignition systems designed by Malossi are based on the state-of-the-art technology applied to racing. Such a new system resulted from the need to overcome the technical limitations imposed by conventional flywheel ignition, which cannot ensure consistent performance over 10,000 rpm and causes severe setting-up problems for racing vehicles.
We made the control unit even more immune to interferences developing an uP STM8 – 8 bit microprocessor with processing speed of 20 MIPS: guaranteeing spark timing with greater accuracy than prior versions!
The MHR Team II includes a not adjustable with 3 trimmers control unit with variable spark advance timing:
- the first trimmer (MAPS) is for selecting the spark advance timing map
- the second trimmer (OFFSET) allows you to shift the selected map ± 2°
- the third trimmer (LIM) used especially for 4-stroke engines, permits you to vary the rev limit between 11.500 RPM to 14.300 RPM and also allows you to disable the rev limiter
It also features 8 preset maps described as follows:
- 1 variable spark advance maps for 4 stroke engines
- 6 variable spark advance maps for 2 stroke engines
- 1 fixed spark advance map
Other essential components have also been revised, such as the high voltage coil, now able to deliver a maximum discharge voltage >40 KV for normal engine speeds from >3000 RPM and an extraordinary ramp up time @10bar> 1750 V/uS.
One of the most important novelties is the new rotor/stator unit, featuring a completely redesigned static component in terms of mechanics and electronics!
