$5 ebay heated grips

[Socal5646]

Just got them in...lol...3 weeks later! Install was a breeze...they get pretty warm! Opted out of using the heat shrink...just put the grips right over the heating element. The element itself has an adhesive back that sticks good enough for you to get the grips back over without moving...bring it winter!

Edit link updated to a different seller! I have not purchased from this seller!

[Jiggles]

Wow, I just installed mine today. Mine were $40 and have an off lo hi switch. I just ordered this $5 one for my other bike, lets see how well they work!

[dubojr1]

I took the leap and ordered a set. I'm wondering if the switch is weather resistant though...

[Bosgarage57]

You could always buy a better switch @ autozone or somewhere couldnt you? Do these go over the grips or under them? I have a hard enough time putting grips on as it is, without having to worry about these pads, but for $5 its worth a shot. Keep is updated!

[Socal5646]

I used my original grips! Just used a really skinny flat head and got it all the way under the grip...then just spin it round and round (breaking up the glue underneath) until it comes off! Stick on the heating element and the grips slipped right back on 80%. A couple of whacks with a rubber mallet finished the job!

compressed air works better than a flat head for getting them off. they literally float right off the bars

43F this morning heading into the office.....new grips work GREAT!

@setasai and I used WD40 to get the grips off and hairspray to get them back on

[Socal5646]

Pic of grip switch installed! Thinking about getting a 3 way toggle and add a resistor For the "low" setting...maybe. Otherwise...bike got soaked a couple times this week with no I'll effects!

[k-os]

I'm guessing the title of this thread is supposed to be $55. I got a little excited when I read $5.

[setasai]

That's an interesting location for the switch. Not bad at all. Coat the electrical connections with dielectric grease if they arent weather sealed.

Do you have them tied into an existing circuit or do you have a relay?

[C L]

They were $5 up until just now it seems. If you go look at the seller's past auctions, its the same item for $5. The dude must've caught on

[Socal5646]

Wow! What a price hike!!!

They are hooked up to the factory accessory lead (10amp) which I added a relay to so it's only hot with the key in!

I'm guessing a good amount of people ordered from this thread coupled with winter coming got this guys wheels turning. Don't worry...he's in china. He's got a buddy two doors down that's gonna start whoring them out soon enough

1.5 watts for each bar doesn't sound like a whole lot of heat.

I'm not sure what mine were on the V-strom, but I think they were a bit more than that.

I've got Gerbin gloves now, so don't have any need for these, but they definately look like they're worth trying for the price.

Where did you get 1.5 watts from? They are 36 watts.

From what did you run the relay? On my V-strom I ran it in parallel with the backlighting for the tach/speedo, which worked great and kept it all really close to the dash where the switch was mounted.
One word of warning...relays can sometimes fail "on". Took me a while to figure out why I had a dead battery after leaving my bike parked after a rainstorm...I'd always just left switch on the high position, since it was never above freezing temps all month.

From the original ebay link at the top of this page.
I'm guessing it's a typo and it should read 3 amps?

That would be 36 watts, but that would be a lot of heat for grips!
IIRC, I think my gerbing gloves are only 20 or 30 watts, and that's wrapping each finger, palm, and the back of my hand.

Yea their power is off "power: 12V 3W"

Still don't see 1.5 watts though

But yes that should say 12V 3A

3 watts total = 1.5 watts per handlebar.

Price is back down to $5.39 with free shipping.

Anyone know what resistor would be needed to do a high/low setup?

EDIT: Looks like this one will be it.

That link doesn't show a resistor.
The easiest way is to do a parallel/series switch, then you don't need a resistor, but it does make the "low" setting a good bit lower than otherwise
(25% of the high).

It all depends on how powerful the gloves are. If we assume 25 watt gloves,


12.5 volts from the bike times the current drawn = wattage of the gloves (25w), so the current drawn must be 2.
Ohms law tells us the 12.5V divided by 2 amps of current is a resistance of 6.25 ohms.
For 50% power (12.5w), we want only 1 amp to pass through the gloves at 12.5 volts.

With a 2.5 ohm resistor, the total circuit resistance is 8.8 ohms
This draws 1.42 amps
since the gloves make up 71.5% of the resistance, they dissipate 71.5% of the 17.6W total circuit power, so the gloves will run at ~12.7 watts, or half the power as without a resistor. The other 5 watts is wasted as heat in the resistor, so make sure your resistor is rated for at least 5 watts.

This is a pretty inefficient way of doing things. Using a 555 chip and a power mosfet would be much more efficient.

You could also just buy one of these for 23 cents, which would give simply run your gloves at 10 watts.

Here's a good resistor for 44cents:

Wait.... no gloves here. I bought the heated grip kit from the eBay source but it only comes with an "ON" and "OFF" switch. I'd like to make it a "LOW" and "HIGH" setup which I know I will need a resitor to do that. I fixed the link above for the resistor. Here it is again:

http://www.bikesax.com/Merchant2/mer...2&Store_Code=B

Now I also know that if I change this setup to HIGH/LOW that I will also need a switch that will toggle to ON/OFF/ON and a new wiring setup. Will this setup calculations be similar to the calcs for gloves?

[dubojr1]

I like this switch. Small and simple. Seems a bit expensive though.

I ordered a couple sets to try, Also Murphskits is a great guy to buy from. He is the person I buy all my Connie goodies from

[Skippii]

Grips, gloves...same principals.

Bought a set for my KLX250s. We'll see.

[Socal5646]

On my second set now...2nd set came with a broken switch...wasn't gonna wait for a switch so went to radio shack and picked one up. $3.50 for the switch! Lol. Still under 10 bucks!

[mikesova]

I just installed the left side and temporarily hooked them up on my KLX250 they work! Did you guys use Huge heat shrink tubing? I don't get what that is for. I just wrapped the bars with some electrical tape, put the sticky stuff on the heaters and wrapped them on the bars. I didn't do the throttle side yet, since I'm out of WD40 to get the grip off the throttle tube.

So far...so good. that switch bracket fits perfectly on the bolt that the clutch lever pivots on. I didn't want to do a permanent mount on these cheapies.

Trying using compressed air to get the grip off the throttle tube.

I ordered a set as well and would like to know what the black tubing is for

I believe it is for insulation on the clutch bars so that heat doesnt so readily get dissipated into the metal bars. I used electrical tape when I installed mine and then I wrapped it in aluminum tape to help spread the heat and secure the grips onto the bars.

I still don't understand where it goes. are you saying it goes on the break and clutch levers to keep from heating up? what are clutch bars? you put aluminum tape over or under the grips?

I believe it goes on your bars BEFORE you put the heating strip on. That way the heat is more likely to travel through the grip, rather than being absorbed by the metal bar.

Exactly. After you remove your stock grips, you have the bare metal handlebars. It's a little more important on the clutch side because the throttle tube is plastic and works relatively well as an insulator.

The aluminum tape is over the heating elements and under the grips. If you do decide to wrap aluminum tape, wrap it in the direction you'll be twisting the throttle or else it might unravel over time.

[bkh2]

I just got these and I'm kind of confused. I've taken off both grips and I assume you put the shrink tube on first to insulate from the bars, then peel the heat pads to expose the sticky backing and stick them on? Once these pads are on, do I use the tape provided to cover them? If not, will they melt the grips when I put them back on?

Or do I use the tape provided (which looks more like electrical tape than aluminum tape..) to wrap the bare bars first, then stick the heat pads on, then put the shrink tubing over that, before putting the grips back on? =[
