These grips are fantastic; they truly are a game changer for anyone that rides their bike year round. Install took 25 minutes start to finish but I'm a mechanic and am very intimately knowledgeable about my bike ('90 FZR600). That's including removing gas tank to run the wires inconspicuously, and putting everything back together. I hooked it up to the ignition (unlike a battery tender) so that you can't turn it on unless you have the key in and turned.

If you're like me and you ride every day, rain or shine, you know that the first part of your body to get cold are your feet and your hands. Now with your feet, you can double layer before putting on your boots and you'll pretty much be warm enough. But your hands, your fingers, they get cold after a while. When it's the morning, and it's 28 degrees and you need to be getting to work, whether you're going 30mph for 20 minutes or 75mph for 55 minutes, your fingers get cold. And with gloves, you can only put on so many layers before your fingers are too bulky and clumsy to clutch + brake.

With these grips, all I now use are a pair of thin leather riding gloves whose purpose are to be anti-abrasive in the case of a fall. But to keep my hands warm for as long as I can sit on the bike itself, the grips really do more than you could ask. Additionally, if it's any temperature outside above freezing, the highest setting will be too warm.

Please note two things: like others have said, the grips are thicker than normal grips. For me, this was a welcome change but for some, it may not be. And, like others have said, you will need a mallet to put them on your actual handlebars. For this, my air compressor saved me a TON of work, this I can't stress enough. If you have a friend with a compressor, buy them a beer in exchange for using theirs. Or buy a little dinky one, they're cheap and super helpful to have at your disposal.

All in all, I love them and would recommend them to any serious rider.

These get nice and warm. Too warm if it's not cold enough outside. They warm up pretty quickly. One minor problem: Sometimes it goes past the first button click (full power) to the second click (low power), so I have to click it a few more times to get full power. Maybe it's just sensitive and I hit bumps while turning it on.

The install was pretty easy, but I removed the tank to make the wiring perfect. Just take care to plan where the wires are going to go. On my WR250R, I sanded down the left handlebar to be able to slide the grip on. Later, when the grips got hot, they slipped around the bar a little. I used some glue to keep them in place. The right grip needed a second gluing because I went too light for fear of messing up the smoothness of the throttle.

I really wanted the Oxford heated grips but I went with BikeMaster to save few dollars. I installed it on my Honda NC700X but any 7/8 bars will do. The clutch side went on really easy, needed some wooden board with a hammer to get it in really tight. I did use some of the super glue but I didn't need it. On the throttle side, the plastic tube has small bumps all through out the tube and as I think about it, I should have grinded it down witha dremel but I just forced it in. Again, wooden board and hammer. I couldn't get it all the way in so it sticks out a little bit but it works fine. I wired it using Honda sub harness so it made installation easy. Instruction is really lame but everything is self explanatory. I would buy it again for sure!

3/7/2017 EDIT: I jumped my review way too early. I did have issues with temperature control unit where I wouldn't get any light on it. I hesitantly contact Bikemaster and get a response right away. We go through troubleshooting and can't figure it out. They send me a new temperature control unit and still the same issue. They sent me an upgraded replacement unit with a LED! It doubles as a voltmeter which I was looking to install. I'm so glad that I purchased from Bikemaster and will definitely rely on them for future heated grip needs. Quick pointer for NC700X riders. Use a dremel to smooth out all the notches on the throttle tube. Makes installation so much easier. I wish they had another star to give for an exceptional product and service!!!

As tested by me the draw is approx 2.5 amps on the highest setting, less on lower setting, on just the battery (engine off, no generator). Ease of installation onto the handlebar is what can be expected for replacement grips; YMMV depending on many factors. In my case I had to use glue on the throttle grip, which means my throttle tube will now need be replaced if I change grips again; your case needs not necessarily be the same. The battery connector cable was long enough to allow me to thread it under the tank, with an appropriate spare amount easily gathered in a neat bundle near the battery; it is fused with a 4 A replaceable automotive fuse (no spare provided, fair enough). The grips' cables connect to a Y coming from the controller, which in turn is plugged into the other hand of the battery connector. The grips operate as promised. Riding 70 to 75 mph in approx. 40 deg. F in dry weather, wearing thin summer gloves, behind windbreakers hand guards, a setting of 2 (out of 5) kept the inside of my hands comfortable, and a setting of 3 kept them very warm. The outside of my hands, well, that was my knuckle head preference for light gloves and not the grips fault. Did not try higher settings to avoid scalding my palms. Cannot comment yet on the waterproofing of the controller; better be good for me, as my bike is naked and the controller will get very wet on a rainy drive. The grips' walls are thick, presumably to make allowance for the heating elements. This results in a fatter handful when clutching my 7/8" handlebar, but unless you have tiny hands (e.g. petite women, youth riders) the difference should not be critical. I cannot comment on the version for 1" handlebars, which do exist. Overall, good value for money and a favorable first impression. We shall see how these grips will hold up.

I put the grips on my '04 DL1000 two month ago while replacing old ones and while adding a new handlebar. Everything fit up pretty good. I used hair spray inside the grips instead of the supplied superglue. They are definitely a larger diameter than what I had before which took a little getting used to but I don't mind it at all. Feels good now. Just yesterday I finally got around to wiring up the heater to the battery. Easy and quick install. I had to add a ring to the red wire, black with came with one. I wired directly to battery. I used a couple of zip ties and the supplied mounting hardware for the controller and done. This morning rode in the cool air and they work great keeping my hands hot at max setting. Great upgrade!
