I believe the stator's charging output is 16 amps/ 260 watts. As the system is capable of handling a 110 watt light bar with a touch left over, you will be fine with the gloves and jacket (44+27= 71) but pretty much at the limit with the gloves, jacket, and pants (44+44+27= 115). I wouldn't go with more than the jacket and gloves, because even though you can provide the watts (barely) to power all three the low amp output means they just won't get very warm- the more pieces you add, the less heat you get from each. I have the whole suit, and on my Suzuki I just wear the jacket and gloves.
On the Harley, which has a 40 amp, 500 watt system, I can wear the jacket, pants, gloves, and socks, and it still gets twice as warm as just the jacket and gloves on the Suzuki. In fact, I have to be real careful because I have given myself blisters on more than one occasion by turning the controller up all the way for too long. I am considering having a local alternator shop make me a high-output stator for the Suzuki, to boost the output up to around 32 amps so I can wear the pants on this bike also.
But honestly, unless it is in the mid 30s I don't wear the pants anyways, and I only add the pants and socks if it is below freezing. If you keep your trunk warm, your body will push more blood into your legs and you will stay warmer.
