Looking for info on what is the best brand of heated grips for the V-Strom. Consideration for ease of installation and of course performance is vital.

I went with a set of Symtec heat elements and a heat troller.
Easy to install, and the set-up works perfectly for me for very little $$
You can get the Symtec just about anywhere and the troller here, and probably a lot of other places.

I installed the Oxford heated grips. Easy to install and they work great.

I have Hot Grips and a heat troller. It's a top line setup. Cost is higher. But from my experience at least get the heat troller. Most reliable, adjustable and does not pull a full load all the time like resistor setups. This controller and the under grip heaters would be the.minimum.

I went with the hot grips and troller. Work great in Maine. Like to be able to control the heat setting.

I was going to go with ATV Symtec wrap arounds over the stock grips and covered with Grip Puppies but the plastic nubs on my Alpinestars summer gloves tear up Grip Puppies. That and the long and happy relationship with HotGrips on the old Wee moved me to stay with them on the Glee. I just didn't want to reduce grip diameter. Also, I didn't want to risk damage to Symtecs with frequent Grip Puppy replacement.

Interestingly enough, large Grip Puppies seemed to have disappeared at the time and I wound up adding Grab-On grip covers. They are much more resistant to damage and go on much easier. They do need to be glued on though. Using Heat Trollers was never a question but a given.
