Tusk Heated Grip Kit for ATVs - Black Rubber Heated Grips with Digital Control

I bought this to use on my '78 Suzuki, so I didn't want to spend a lot of money. I installed it myself and have been using it for a couple of months. So far, I'm very happy with it. It installed easily, although I added a fuse and relay (another $10), for safety and current-flow reasons. A switch and resistor are included, and the wires were more than long enough for my application. The installation took only about an hour, largely due to my indecision as to where to route the wires and where to place the switch and relay. The heaters provide a nice amount of heat and greatly improve my comfort durign my morning commute. (in temps down to 25F so far) The high setting is toasty in frigid weather, and the low setting is a nice comfort on cool mornings. I recommend this product f you are comfortable adding wiring to your bike, but be sure your charging system can handle the extra current and install a 12V automotive relay so you won't run your battery down if you forget to turn off the system. A fuse is also a good idea, because the heaters draw a lot of current, and most of the wiring will be under your gas tank.

"Yeah, they get warm. Sorta. Not even enough to feel through my insulated gloves. There's absolutely no way these will keep my hands warm. I suspect it might have something to do with my grips, which are foam, not rubber. I think the foam insulates too much for these to do their job. Or maybe they just suck. I guess I won't know unless I replace my grips with something else. The low setting utilizes a ceramic resistor that gets way too hot to touch, and the leads out of the resistor are made of a stiff wire that feels like it will break if you flex it much, so beware of that when you install. FYI, you're going to want to pick up an inline fuse holder or run the risk of catching wires on fire should something go amiss (like maybe that resistor lead popping loose and grounding to the frame). Also, a relay rigged up to your key switch wouldn't be a bad idea, otherwise you might accidentally leave them on and kill your battery." EDIT 12-06-12: Just finished taking off the foam grips and replacing them with gel grips. HUGE difference! They most definitely get warm now, much hotter than I expected based off my first time around. So, for future reference, these heating elements won't work well with foam grips, but should work well with more solid styles. I'm still leaving off 1 star because of the extra bits needed to wire them up the way they really need to be, and because I simply don't trust that low setting resistor.

I have had many sets of these on many different bikes, and I've never had an issue with any of them. They install easily, fit on any bike, and function great. I generally never have to put them on high, as low is usually enough - even when riding in 30-40 degrees (F). You usually have to add a little 18g wire for the installation. Can be installed in about 30 minutes on most bikes. Has a trusty robust toggle switch, which may not look as nice as other options, but will not let you down after 6 months like the push button set ups. I go through a lot of bikes, and this is definitely my go-to for heated grips.

I purchased these grip heaters based on cost. I installed them under my existing grips and mounted the switch in a 2x3x1 inch project box from Radio shack. I also mounted the resistor for low heat onto a frame rail beneath the seat where it will not come into contact with anyone or thing as it can get quite warm when running on low heat. The design is such that one needs to have a substantial loop of wire on throttle side to lessen wire breakage. I suspect the wires may need to be repaired after a period of use, the length of use depending on ones throttle activity. All in all a decent product for the price, they warm the grips in a timely fashion. I have not used the heaters long enough to state how long they may last. (March 16, 2014 Update)I only got about 3 weeks of riding time before the soldered wire connection on throttle side broke. I repaired it with a new soldered connection,double checked that there was plenty of slack for flex and received the same broken connection within a weeks riding. I would not recommend these heaters for M/C use with twist throttle, would probably work well on ATVs or snowmobiles with a thumb type throttle. They did work well until wire broke

Easy Install, works and the provided switch looks retro-tastic! They will make you wonder "How did I go so long without grip heaters?!?" - Life changing stuff if you're like I was and have never used them before. They're not the highest quality but hey, what more could you want for $20.00? They are made in Taiwan and the Taiwanese are known for decent products (at least in the Vespa world). ------------------------------------------------------------------------------- 2 Week Follow-up: I just ordered a second pair as a Christmas present for a friend. The switch needs to be fitted with a washer on the bottom and a rubber grommet on top to keep it tight and waterproof (if dash mounted or glovebox mounted). These items are not included with the kit. A Large-frame Vespa flywheel wavy washer works great for this. My only legitimate complaint is the cool looking switch cover is already fading, scratched and has warped a little bit. While I'm here ~ If you're installing on a Vespa PX, tap into the grey wire under the horncast for power and run the ground to the black wire in the harness. That extra load just about maxes out the electrical system but does not excessively drain the battery. Do not frame ground the grips and connect directly to the + on the battery even though they do get hotter that way. If you insist on running them off battery to get the full effect, I'd probably mount a 2nd battery in the glovebox and recharge it frequently with a trickle charger. Be sure to ground the grip heaters to the negative terminal on the second battery though.

These came with the wiring and instructions for the heated thumb warmer add on kit. They came with no wiring, information or instructions for the heated grips. Also they are not hi/low heat only on or off.
