Amps for accessories

Does anyone happen to know how many extra amps there are available for accessories? Since I start riding early in the season and on backroads I’d like to wire for a heated vest ( 8 amps) and a Garmin GPS (I believe 1-2 amps). These two accessories work well on my Yamaha xt250, which has a spare 10amps.

Thanks.

Also, some good reading just arrived from Helm Inc.

While I know the output of the stator is quoted as 190W on various sites, threads and replacement parts sites, I have no idea what the actual power draw is under normal operating range from that (since as you noted, available power = output power - power used to run the bike). The XT250 has roughly the same stator output.

No questions, GPS is fine, and if GPS is not fine, I will question my life and everything I thought I knew to be true. The heated vest though... 8A @ 12V = 96W, and it's likely to run at peak power more often than the GPS will. That's a lot of watts and the CT125 is already effectively on a power reduction kit with the full LEDs.

The bike comes with a kickstart and Warro proved you can start it without a battery so you'll never be stuck up a creek without a paddle even if you're running anemic (you might be cold, but you'll still roll). You can also use that to test if your accessories will work without drawing from the battery, or measure the voltage before and after a long ride with the accessories turned on.

Hey , take a look at Gobi heat vest- runs on rechargeable battery pack on high for 3-4 hours, more

There are lower power heat vests. I saw at least one that ran at 47W or so, so either it's not as hot or it is more efficient. I think if you're running it fine on the XT250, it's probably fine on the CT125 as long as the XT is the EFI version (2013 or later), but I'd probably do a temp install and do some testing to know for sure.

No one has really put out any numbers for available wattage, here, on ADVRider, on Youtube, or anywhere else as far as I'm aware, and I've been looking for quite some time. The only thing I know for sure is that you can charge a GPS off it, but that's setting the bar really low. I've seen numbers as high as saying you'd be slowly draining the battery running that heated vest on full, and as low as saying you'll be 100% ok.

IMHO, the standalone battery ones are the best option, and then recharge a spare battery on the bike while using the other one on your vest. recharging a battery will take considerably less amps than running it directly. my .02

Thank you all for your responses, I’ve learned a lot and this led to some more research. Currently, my dealer is going to call Honda and ask them about the excess amps for accessories. Also, I have found a hardwire vest that uses only 3 amps instead of the 7-8 amps used by my original 1993 Gerbing vest, purchased from Gerbing himself when he was running the business mostly by himself. While the battery operated vests looks interesting, I feel that a hardwired one is the best fit as I go on multi-day/week trips on backroads with no support beyond a folding solar panel and Goal Zero charger. When my dealer gets back with his answer on the amps I’ll be sure to post.

36 w should def be doable, but def curious as to what honda says, looking fwd to that.

one more argument for the battery vest: if you get a flat or stranded you can still stay warm w bike off and not tethered to it. I have a friend that has one of these for working on his vintage cars in his barn (different brand) but it def works well to keep the core warm.

The idea of also having a battery heated vest for wearing on my bicycle and extending the season is also very appealing...so I may need two vests!

So I've been experimenting with this on a trial and error basis. Running a pair of AUX BEAM fogs rated at 34 watts for the pair - no problem. I just added a set of Koso heated grips which take about 40W at full blast. Those shut off automatically if battery voltage dips below 11.5VDC, and on a longer ride (1 hour or more continuous) I have had it happen, meaning the combined load of ~74 watts is overwhelming the capacity of the bike, albeit slowly. So I see 60W to play with as a safe bet. Now for heated gear, W&S makes a 65W liner that could marginally work, if that's all you're plugging in. Better yet, the 12VDC HLS should be much less - maybe 45 watts or so - so that's definitely a safe bet.

I'm dealing with the winter by using battery powered accessories. So my core is W&S HLS and I'm using KLIM's heated Resistor gloves for my hands. I've also got a California Heat heated balaclava that I tested here. With this gear, and my Koso grips on high, I have ridden for over an hour in single digit temps here in NJ. Just beware that you have to time this right! Once the batteries run out, they're done, and you will freeze to death trying to ride at those temps without active heating!
