I am interested in getting some hand guards for one reason. To keep my hands a little warmer during what poses as winter here in AZ. I wanted to do it at a minimum of messing with my V650 (as in removing the bar ends). So I found these:
and Barkbusters makes a more expensive, equivalent unit. I probably won't even keep these things on year round unless we have a gigantic cicada infestation during the warmer months. So, easy on and easy off as I see it. ANYBODY HAVE THESE STYLE? Thanks
My brain dump on cold weather riding...
I find the effect hand guards on hand warmth is imperceptible. They look nice but they do not do anything wrt warmth I've found, although others may disagree. Insulated motorcycle gloves and/or heated grips will provide much more comfort and be more practical for less money.
I currently own three pairs of gloves and switch between them as the weather dictates. Normal gauntlet style gloves for warm and hot weather, waterproof non insulated gloves for cooler temps, and insulated and heated Gerbings gloves for cold weather. I would suggest you combine the last two types into a single pair of waterproof and insulated gloves and if you still have cold hands then add a pair of oxford heated grips. Heated grips only heat the palm of the hand though so in -50F/10C you will likely want a combination of insulation and heat if you are on the bike for any length of time at highway speeds.
As a person living in the second coldest national capital city (we got Moscow beat but Helsinki, Finland is coldest) where I spend a lot of time outdoors skiing/hiking in the winter and sometimes motorcycling in late fall and early spring, it is important to understand the relationship between time of exposure, exertion(body heat generation) and wind chill. Weather temperature by itself is irrelevant in determining warmth. You can sweat exerting yourself at -20C if you are well insulated and protected from the wind. Exposed skin, like your nose though, will burn at the same temperature though and suffer frostbite after 20min if it is not covered. City riding for instance, even in the coldest ride-able temperatures (0C/32F), will not likely make you that cold on the bike but an hour on the bike at highway speeds at 40F/5C will freeze you without heated gear. Also a warm core will mean warm hands and feet. Your body restricts blood flow to the extremities when it gets cold to protect the important organs. A warm core will mean warm hands at colder temperatures. Cold hands and feet are the first signs your core is having a problem staying warm.
A heated jacket liner (with heated collar and arms, plus heated gloves is the ultimate solution. Heated gear is great on a bike in cold weather because you are not generating body heat through exertion but losing it rapidly due to excessive wind chill (heat lost = 60mph X temp X time exposed). The wind also makes insulation less effective due to the fact you cannot prevent all the micro air leaks that occur at this speed and the body is generating minimal heat due to exertion. A heated jacket liner and heated gloves provide the ultimate cold weather comfort and are not affected by air leaks. Heated grips are more versatile (in between temps) than heated gloves but do not provide the same level of comfort (heated gloves heat the fingers and back of the hand, the parts that get cold) in cold temps or on long highway rides. The only downside to heated gear is the intial investment and the fact you need to connect up every time you put your gloves on or take them off. For this reason it works great on the highway for trips of .5 hour or more but is more of a pain for city commuting where you are riding 15-20 min at a time at slow speeds in heavy traffic.
Also suggest looking at a pin lock or fog city visor insert if you have not already got one, as visor fogging is a common issue at colder temps. Budget priced motorcycle tires may work fine at normal temps but in cooler temps are more likely to have traction issues compared to premium tires that use more advanced rubber compounds that are less effected by the cold.
* I have a Gerbings MD jacket liner and size LG Gerbings T5 heated gloves for sale in the for sale section along with the requisite dual temp controller. I love it in cold weather but am selling as I have an excess of cold weather motorcycle gear and since I purchased I have moved to an area where my early spring and late fall riding now is in a large city, where I do short commuting trips at lower speeds, where it is not as useful. It truly is the cat's pyjamas though for back road and highway rides of .5hr or more at 60mph/100kph. You can ride at these temps like it is 70F out.
