Hello,

For many years I've ridden motorcycles, and still do, but I just purchased a GTS 250 ie for around town riding and am enjoying the thing immensely. The CVT will take some getting used to; every once in a while I absent-mindedly pull the "clutch" lever to up gear to second. But, with experience, that'll change.

I am delighted to find this site. Friendly and informative folks, and lots of information. The article on installing a power-plug and turn signal announcer was really well done, and will be a big help for my first project.

I don't know if this is the appropriate forum for my question, but can someone tell me the wattage output for the GTS 250 alternator?

The GTS (at speed) will produce 24 amps when cold (approx. 307 watts) and 21 amps when warm (approx. 269 watts).

We run 2 Gerbing Heated jacket liners and 2 sets of gloves with the dual control thermostats for each, so the gloves and jackets can be contolled separately. We also never turn anything on until we're moving. Switches are OK but are always giving you FULL power and always need to be turned off when stopped, even at a stop lights.

The alternator can handle the heated gear. We're careful when we turn our stuff on and always adjust it lower when warmed up. Turning the thermostats down uses less power form the scooter electrical system.

With 26k on my GTS now I'm still on the original battery.

Hope that helps,

There we go! That's what I was looking for. Thanks. If the ~8 amps (96 watts) leftover for accesories is correct then there is not a lot of margin for lights and heated gear. My Gerbing jacket liner draws 55 watts. Maybe some extra for gloves but that's about it.

If you do something interesting with it, please post it for us!
