Gas bikes are always going to win the range argument, though I think it will become less and less relevant over time.
I doubt range at 170 mph really matters hugely.. if sportbike riders hit those speeds outside a track, I would hope they do so only for a very brief period of time on a road with little traffic.
What's a sportbike tank hold? 4 gallons? This R32 got
7.6 mpg at 170 mph, I doubt a bike will do much better.. so talking
30-40 miles at those speeds.
The Lightning superbike
returned 600 Wh/mile at 215 mph, 120 Wh/mile at freeway speeds. 170 mph is probably about 400 Wh/mile .. so a 12 kWh pack would be good for about 30 miles.
Equip the Lightning with the 22 kWh pack and an electric bike has more range than a gas bike. (220 freeway miles, versus maybe 160 on a gas literbike).
When Brammo and Zero released their first bikes in 2008, there were a lot of arguments against electric.
1. Very poor range (20-30 miles real world).
2. Slow charge times.
3. No loudpipes!! / No soul / etc
4. Limited top speed
5. Slow acceleration
6. No passenger space
7. Expensive ($12k enertia, $8k base Zero X) relative to competition
Those arguments are starting to fall, or at least diminish in importance.
1. Range - Empulse and Zero can return 70+ miles in real world riding, especially at 40-50 mph speeds
2. Empulse charges in 3.5 hours on J1772. Zero charges in 1h on CHAdeMO. Still room to improve..
3. ..
4. Zero can do 95 mph (or 105 with race gearing), Empulse can do 100+
5. Latest Zero lineup is 4-5s 0-60, Empulse is around 4-5s 0-60
6. Both Zero S and Empulse have passenger pegs now
7. Still a problem .. we have the $11000 Enertia Plus and the $7995 Zero XU .. both far more capable than their 2008 brethren.
