Moto Guzzi Controllo Trazione

[pikipiki]

Does anyone know anything about it?
I have no experience of bike traction control only car systems.

How does V7ii traction control differ from 1400?
How differ from Aprilia or Ducati?
How is power reduced? drop cylinder? retard timing, butterfly valve?
How sensitive is the system to tyres or poor battery?
Can you turn off TC independent of ABS.
Do bike systems do what some car systems do - If you over cook things drop power to punishment mode for a few seconds to allow ABS to re-prime its self?

Sorry I find practically no information regarding Guzzi TC on the net?

I can only talk about the California 1400, as it's the only bike with traction control that I have had experience with.

When I first starting riding the bike, I was wary of the traction control, and nervous that it's intervention may have negative experiences for me.  Nothing could be further from the truth.  It is very unobtrusive, and the only way I know it's kicked in is the flashing light on the dashboard, and a slight loss of power.  This is particularly noticeable when ascending a gravel road, but occasionally I will see it flick on momentarily on the tarmac too.

I believe the 2nd spark plug is initiated with traction control, perhaps to induce a more uneven power transmission to assist in regaining traction.  Power of course is under the control of the ECU, so may be reduced also.

Traction control may be turned off independent of ABS, but the warning light is permanently on reminding the rider is is disabled.

Traction control kicks in when the wheels are running at different speeds linearly along the road, i.e. they may be rotating at different speed because of different diameters etc.  It is calibrated initially, and if a different tyre size (or maybe brand) is fitted, may require recalibration by travelling at a constant speed of 30 kph for about 10 seconds.

I'm now a fan, and see as a complementary action to ABS.

It re-calibrates, that's good.
Its over sensitivity to tyre sizes , battery charge and ride-by-wire throttle that I'm not sure about.

It will take some time to trust these things like in the last 20 years of fuel injection the Guzzi fan crowd still has to fully accept it.

The tracion control of the cali is more sophisticated then the v7, the ride by wire makes that it can totally control what the engine does. The v7 has to do it by changing fuel and sparks, but can't control air amount.

Traction control has real benefits for motorcycles.
not only when fitted to the bike but when fitted to other vehicles.
e.g. more sophisticated features like VW City Emergency Braking benefit us as the more cars have this system the less likely we are to be injured by bad drivers.
but for me as maintaining my bike my self is an important part of the motorcycle experience I'm unsure if I want traction control on my bike.
If the system cannot be turned off and is linked in to the engine ecu and both wheels it can make diagnosing problems difficult.

So for moment abs gets a yes, tc not ready to adopt.
