TecMate OptiMate 4 Dual Program Battery Charger
Ordered this charger after I left my bikes electrical systems on all night in the garage. After receiving the charger and setting it up I let the bike charge over night and was delighted to see the battery seemed as good as new.
Have now done this a total of two times, this charger has more than payed for itself. I cannot really comment on the trickle charge functionality as I ride year round so I have no use in storing my bike.
Overall, a very useful piece of gear, definitely a must have for any type of bike.

This is perfect for charging BMW Canbus equipped motorcycles! Works as advertised. The BMW dealers chargers are very pricey, this works just as well for a lot less! Highly recommended!

Works well, great value!
I contemplated buying the OEM BMW charger for my new R 1200 GS-W but could not justify paying $100 more for the OEM charger. I was concerned after reading other reviewers who had dificulty understanding the directions for the Optimate 4, but it came pre set for the BMW CANbus system. It was just plug and play and works very well. It appears well made and is very easy to connect. A real value for a quality charger. Just remember that the directions are written for an international audience. That's why they may appear cryptic, but it's really quite simple to use.

Nice, multipurpose charger
I've used this charger for everything from a Porsche, connected via the cigar lighter, to a lawn mower, to an actual motorcycle. Following the mfrs guidelines for both the vehicles and the charger, I was able to top up any battery I've encountered. My only failure was a 10-yr-old battery that was so deeply discharged that it couldn't be saved. Highly recommend.

Just plug it in.
Easy to use. Specific model for BMW CanBus. Better value over BMW charger

Does exactly what its supposed to do--just plug it in when the bike is in the garage, and forget about it. Your battery will always be topped off and in perfect condition.

Great display and features
Does it all. You know exactly the state of charge and function with this charger due to the intuitive and easy to read display. Way better than my "other" chargers! Very happy and a great price.

Works great and is a much less expensive than the BMW Canbus charger
I looked around quite a bit to see if the BMW Canbus charger could be purchased inexpensively and it wasn't available. After I read the reviews here I decided to go for this charger which was $50-$80 less and I'm glad I did. the OptiMate 4 Canbus charger worked great on my 2009 BMW F800ST. I knew my battery was low because our weather has been horrible and I've barely been able to ride and get my bike charged up. 2 days after the purchase of this charger I plugged this in to my bike as the battery was dead. The charger came set to the BMW Canbus mode so other than finding a wall socket it took care of the rest. I switched modes and charged my riding lawn mower too. There are a number of lights on the charger so you really need to see the instructions the first time but once you've seen them you should be all set. I'd buy another in a heartbeat. I've only had it a short while and I certainly got my money's worth.
Keep in mind that if you have anything tied into the Canbus power when this charger starts you may turn on that device. I had a GPS device tied into the Canbus and it turned on due to the charger. I ended up directly wiring the device to the taillight to avoid the Canbus issue.
