Honda Hornet 600- can battery run heated grips & Waistco

[Meerka Mouse]

Hello

Returning rider after some years child-centred absence (it's a bitch to ride with a Bump).

My poor neglected Hornet 600 is finally getting some attention. Due to the extraordinary price of getting bikes maintained in a workshop in the NL, looking at fitting new heated grips and waistcoat with the help of a friend.

(I'm a soft as hell rider and we've book a weekend long distance travel, could be 8 - 10 hours' riding depending on the weather)

Technical question:

The battery is 12V - 6Ah according to the Owner's Handbook.

The Oxford premium grips "draw under 4A" according to the specs on the brochure.

The Oxford heated waistcoat is for 12V vehicles. 4 heat settings (I assume the warmer it is, the greater the drain).

I can't find any more detailed information than that.

Is the battery going to be able to cope with those two drains?

1) will it cope with both on, all the time, without draining?

2) could it cope with one or the other? (ie can I swap between the two, use the grips for a while then the waistcoat).

If anyone has any ideas I'd be very grateful!

(the bike shop told me that it can't be done which I *know* is untrue as I've had both attached to my previous Hornet for long distance frequent winter commuting, many years in the past. My wonderful then-mechanic worked it out carefully that the total drain was less than the battery could provide and it worked perfectly).

Thanks

Simple answer yes it will cope, just make sure it's only being used when the engine is running.

With the headlight presumably always on too, the charging capacity will be barely coping if both are on for long.

A quick google shows one Hornet 600 can produce 333w at 5k rpm.

Lights should be well under 100w for all of them.
4a max for heated grips gives us another 50w or so.

Seems like plenty of spare room to me? (Not sure how much average background stuff takes - would expect fuel pump won't be much as usually they've just got short cycles, of course there's spark plugs, ECU etc too).

Hmm thanks for the explanation and clarification.

Sounds like I can have both but it's wiser to alternate them or only have both on at once for short periods. Usually leave the bike on tricklecharge at home but when we're going for the weekend away, that won't be an option.

Many thanks

move up to a newer generation of battery?

you've got a ytx7l-bs, as batteries have developed since then you may be able to fit a newer / better generation of battery in it, a ytz10s perhaps?

you'll need to check the size, but the Ah will be better as will the cca

the other option is if you do go away disconnect or turn off your heated stuff 20 mins before your arrival to give the battery a chance to charge up fully.

I did have to do this on my ex's scooter in order to get a charge in the battery as the output of the genny was insufficient.

Contrary to what I said in the first paragraph against my second, this is only going to be a problem IF the genny is insufficient

mmm I'll turn them off 20 mins before arrival then. It won't be so bad when a journey ends at home as I can trickle charge it then (though is draining the battery that much bad for it?)

It's the sort of thing I can find out by experience as long as I'm careful to end up at home, maybe.

Really looking forward to the new trip, it'll be so good to be on the bike again.

Yes the hornet 'should' be able to cope but there will be virtually no spare capacity in the battery or charging system.

The way around this is to change the rear bulb for an LED one along with the pilot light and all the idiot lights in the clocks. This will give you a little extra overhead.

[Rogerborg]

It'll save about 4W per bulb, which quickly adds up.

For context, I run 4A / 48W heated grips on my Enfield, with LED instrument, tail, side/running (x5) and indicator bulbs. With the headlight on and grips on full, it holds charge at fast idle and provides a surplus while riding (ammeter FTW).

I'd be astonished if your Hornet provides less, and it'll already be dumping the surplus through the reg/rec - you might as well use it to heat yourself.

We are all looking at the grips/vest running at maximum load here. When I use mine they don't stay up at the max setting for long, maybe about 10 minutes. After that, once the grips and my gloves have warmed through they get turned down to about a quarter. Same will probably apply with a heated vest, quick blast then turn it down.

Should be fine
