For what it's worth, I've owned an Empulse R since January, and have put about 9000 miles on the thing so far. I can share plenty of thoughts if anyone wants them.
Two big things to keep in mind:
1.) You will never, ever, ever begin to even come close to making up the price difference in gas costs. Unless you're comparing to something at a Panigale price point. Yes it's hilarious to annoy your friends by riding in silent circles around them while they are filling up at the gas station, but I'll have to keep the bike for 20 years or something to make up the dollars. If you're even beginning to think about doing it for the gas costs, go buy a $1000 SV beater instead. After sweet rebate dollars back, net cost to me will be about $16k.
2.) It cannot do long distance. And I don't mean that in the sense that that phrase usually entails -- like "oh ha ha you have a supersport with clip-ons, you can't do long distance on that." You can ride cross country on an uncomfortable bike, you can bend all sorts of motorcycle rules and genres and use bikes for things they're not supposed to do . . . . but this is different. It literally in the actual sense of the term 'cannot' cannot do long distance.
Those two being out of the way, if you are still interested in getting an electric, let me share with you my impressions of owning the bike:
- Handles amazingly. Utterly goddamn amazingly. The combination of the things you can do with a frame that doesn't have an engine in the way + the weight distribution of no gas tank + no engine vibration + no gyroscopic force of reciprocating mass = holy SHIT.
- Goes off the line like nothing I've ever experienced. If you get good at the powerband (yes, there is a powerband) it goes off of other gears pretty damn well too. Once you are at speed it feels like a 650 twin, sort of.
- Maintenance is tires, brakes, chain, fluids, and that's about it.
- Cost of electricity is negligible. I was all nervous checking my first month's PG&E bill for the huge dent I was sure the bike was going to make, and I couldn't even tell the difference.
- I love having the gearbox. It's a bit industrial (apparently it's from a supermoto racing application) and takes some getting used to not operating the clutch at starts and stops, but it is awesome to have.
- The noise is fantastic.
- Bonus: you get to make yuppies plugging in their Priuses at charging stations very very nervous.
I could go on probably forever, but suffice it to say that I love the hell out of it, it's the absolute perfect commuter, and it has caused me to stop riding all my other motorcycles. Feel free to pester me with questions if you are curious about any aspects of ownership/whatever.
Also, it is tons of fun on the track!
