Moto Guzzi V85 TT - Owner's Manual > MGCT system (Moto Guzzi Controllo Trazione)

The MGCT system is a device that helps the rider during acceleration in manoeuvres with the aim to increase the stability of the vehicle, especially on slippery surfaces or in conditions that can cause sudden slippage of the rear wheel. In these situations, the MGCT automatically intervenes by reducing engine output within the limit imposed by the grip conditions, contributing significantly to the maintenance of stability of the vehicle. The rider is entirely responsible for riding at an appropriate speed in relation to the weather, road conditions, vehicle load and state of the tyres, and allowing for an adequate margin of safety, taking into consideration that the physical limits of vehicle grip on the road never have to be exceeded. Under no circumstances can MGCT compensate for any rider error or improper use of the throttle.

CAUTION

THE MGCT SYSTEM DOES NOT PREVENT FALLING IN TURNS.

DO NOT SPEED RECKLESSLY. LIMITS OF GRIP ARE DETERMINED BY LAWS OF PHYSICS, WHICH EVEN THE MGCT SYSTEM CANNOT OVERCOME.

WARNING

THE MGCT SYSTEM IS BASED ON THE RECOGNITION OF SPEED DIFFERENCES BETWEEN FRONT AND REAR WHEEL. FOR THE SYSTEM TO PERFORM CORRECTLY IN ALL CONDITIONS, THE PROCEDURE MUST BE PERFORMED EACH TIME A TYRE IS REPLACED EVEN IF ONLY ONE OF THE TYRES IS REPLACED.

TO CALIBRATE, CARRY OUT THE PROCEDURE OUTLINED IN THE "ADVANCED FUNCTIONS" CHAPTER

To deactivate the MGCT system, see the "Advanced functions" chapter.

The MGCT system indicator lights consist of orange warning lights on the upper part of the instrument panel and an orange MGCT indicator light on the RH part.

Flashing mode:

• Off with the vehicle in gear: the system is working, but is not active (normal condition).
• Flashing quickly with moving vehicle: the system is up and running (conditions of low grip and intervention to reduce engine power); we recommend the utmost caution because the grip limit has been exceeded; restore the vehicle safety conditions by gently reducing the throttle opening.
• Permanently on with the vehicle in gear: the system is disabled and will not intervene in case of loss of grip.

• If deactivation is intentional, we recommend reactivating the system as soon as possible.
• If deactivation was NOT intentional, there is an MGCT failure: in this case you must contact an Authorised Service Centre for the diagnosis and reactivation of the system.

To ensure maximum safety of the vehicle it is advisable to keep the system active.

Deactivation may only be necessary if starting on very low grip surfaces (mud, snow, gravel) on which intervention of the MGCT could prevent the vehicle from moving.

CAUTION

THE STATE OF THE MGCT SYSTEM CAN ONLY BE MODIFIED WHEN THE KEY IS SWITCHED TO ON.

NOTE

AT VEHICLE START-UP THE MGCT INDICATOR LIGHT FLASHES AT THE SAME FREQUENCY AS THE ABS INDICATOR LIGHT, INDICATING A DIAGNOSTIC PHASE OF THE SYSTEM. IN THE ABSENCE OF ERRORS, BOTH INDICATOR LIGHTS TURN OFF AT THE SAME TIME WHEN EXCEEDING 5 km/h (3.11 mph).

IN CASE OF ABSENCE OF FLASHING AT START-UP, THE SYSTEM MAY NOT WORKING, PLEASE CONTACT AN AUTHORISED SERVICE CENTRE.

WARNING

IF DISABLED BY THE USER, THE MGCT SYSTEM KEEPS THE STATE OF INACTIVITY ONLY IF THE VEHICLE IS OFF BY USING THE ENGINE STOP SWITCH (RUN-OFF).

CAUTION

IT IS EMPHASISED THAT THE RIDING AUXILIARY SYSTEM CANNOT CHANGE THE PHYSICAL LIMITS OF GRIP AND IS NOT A SUBSTITUTE FOR PROPER MANAGEMENT OF POWER, BOTH ON STRAIGHT STRETCHES AND IN TURNS.

THEREFORE, IT IS RECOMMENDED TO ALWAYS USE THE VEHICLE WITH THE UTMOST CARE AND IN ACCORDANCE WITH THE REGULATIONS IN FORCE.

NOTE

WHEN GOING OVER ROAD JOINTS, RAILS AND/OR ROADS FULL OF POTHOLES, BRIEF ACTIVATION OF THE MGCT SYSTEM MAY OCCUR. SUCH EVENT APPEARS UNDER NORMAL OPERATION CONDITIONS OF THE VEHICLE.

CAUTION

A POOR STATE OF MAINTENANCE OF THE TYRES (PRESSURE TOO LOW OR FLAT TYRES/WEAR) CAN RESULT IN ABNORMAL OPERATION OF THE MGCT SYSTEM.

IN CASE OF REPEATED INTERVENTIONS OF THE MGCT SYSTEM, EVEN ON ROAD SURFACES WITH GOOD GRIP OR SMALL THROTTLE OPENINGS, IT IS NECESSARY TO CHECK FOR WEAR AND/OR THE STATE OF INFLATION OF TYRES FIRST. IF THE PROBLEM PERSISTS, DEACTIVATE THE MGCT SYSTEM AND CONTACT AN AUTHORIZED SERVICE CENTRE.

CAUTION

IN THE EVENT OF MALFUNCTION OF THE BATTERY, THE ABS - MGCT SYSTEM TURNS OFF.

IF THE GAP FOR ONE OR BOTH SENSORS IS NOT WITHIN THE TOLERANCE INDICATED BELOW, TAKE THE MOTORCYCLE TO AN Authorised Moto Guzzi Dealer
