I was just reading the spec sheet on the new Tiger- 950 watts (!!!) output. Here's what the brochure says about it:
It sure sounds like they've been keeping an eye on electrical issues with other motorcycle brands and making damn sure they avoid them. | ||

Or looking at any car made since about 1960.  | ||

Yep, this is nothing new. I know Gold Wings and at least some BMW boxers use completely external, belt-driven alternators (as does the new Motus). Are permanent magnet, enclosed alternators otherwise universal on motorcycles? I'll be interested to see the physical arrangement of the Triumph alternator. | ||

Nope, I think the late 80's yamaha radians used true alternators. The only reason for permanent magnet systems is that there are no brushes to wear out, and fewer coils. So it's probably a case where if you can live with limited power output (like a motorcycle), they are a little more simple and a little more durable. | ||

The only reason for permanent magnet systems is that there are no brushes to wear out Even if you didn't care about the wear, I'd think you couldn't run brushes in an oil bath either, which would preclude mounting inside the engine or primary. | ||

My 79 Honda CBX used an external alternator mounted behind the cylinders. Brushes lasted around 40000 miles and were easy to replace. The only issue these had was with the clutch that was between the engine and the alternator. It could get a little noisy. | ||

honda st1100 and 1300s use external alternators too. | ||

All air/oil gixxers, Bandits, GSX1100G,... Little automotive Nippondenso alternator behind the block. | ||

BMW boxers have been using external alternators for ages. They're mounted on the front of the engine (right behind the engine cover) and are driven by the crankshaft. They are the same Bosch units that are used on some VW cars. My 94 oilhead (still have it 17 years later!) has a 750W alternator. I've never had a problem with it. Just for reference 746W = 1 hp. |
