What Your Spare Watts Can Run
None spare20–42W stators
Stock loads only
- Stator just trickle-charges the battery
- A GPS or USB charge (~5W) outruns it
- Add a higher-output stator to run accessories
~15–35W spare70–90W stators
Light accessories
- GPS or phone charging (~5W)
- One small LED accessory light
- 90W bikes: a cooling fan (~35W)
- Not enough for heated gear
~110W+ spare168W and up
Full setups
- Heated grips (~25W) + heated vest (~50W)
- LED aux light pair (~30W)
- GPS + USB charging
- Still room to spare
Rough draws: GPS / USB ~5W · heated grips ~25W · cooling fan ~35W · LED aux pair ~30W · heated vest ~50W. Pick combos that stay under your spare number.
All bikes listed run a regulated DC charging system. '24-26 figures: headlight models (EXC-F, XW-F, 300 XC-W) run 196W; closed-course SX-F and XC-F run 70W.
Spare watts is a rough accessory budget: stator output minus ~55W for the FI pump, ECU and ignition. None means the stator can't cover its own draw at rated output, so the bike leans on the battery. Lit models spend another ~25-30W on the stock headlight before you add anything.
