Not Apples and Apples to race a production bike against a prototype built for racing.
True. I'd like to see grid sizes in TTXGP improve to the point where the prototypes can be separate from the street bikes.
If Brammo tried to sell these prototypes they'd have to charge north of $30,000 to break even.
Ah.. at least as much as Lightning, for sure. And Lightning is using a production electric motor vs a prototype electric motor..
Ironically, within a few years Zero's revenue-generating commercially available < $15,000 bikes will beat Brammo's money-losing prototype/show bikes even on the track. At which point it will be Game Over for Brammo, if not sooner.
It'd be awesome if/when electrics develop to the point where you could buy a 120 kW race-ready bike for < $15k. I think we're a little ways off from that yet .. like 7-10 years away .. but rapidly improving, as Zero is showing.
Big costs that can come down to bring race-level power to street bikes:
1. Controller. Brammo, MotoCzysz, and Lightning (IIRC) all use a
Rinehart motor controller. This is uber-powerful, and uber-expensive. Sevcon Size 6 is around $1000 (IIRC). Rinehart is around $8000-10000. I don't know what controller Brammo is using .. but the PM150 Rinehart is 450A RMS continuous up to 360V DC. The Sevcon Size 4 Zero uses is 140A RMS continuous up to 116V DC.
2. Motor. Brammo uses a prototype Parker GVM motor, Parker says 130 kW. Because it's a prototype it's basically unobtanium, but figure it'll cost a few grand when it goes into production. Lightning uses a Remy HVH250 motor,
online pricing $8-9k. In comparison, a stock ME0913 is around
$800. Plus, the huge motors need much better cooling systems.
3. Batteries - 10C is pretty strong discharge for non-lipo. Brammo and Lightning are both packing 14+ kWh into their bikes. EIG pouch cells (as in the 2012 Zero) are rated for 10C peak, 5C continuous.. so you'd need at least 12 kWh (ZF14.5 in Zero parlance) to power the motor.
4. Data acq systems. Brammo and Lightning both use Motec dashes iirc. $$$, awesome for prototype systems. Brammo and Zero both already have more basic data acquisition systems in their street bikes .. good enough for a street type superbike.
The fancy brakes and suspension bits, wheels, etc are probably about as cheap as they're going to get. CF fairings might get a little cheaper.
In 10 years time .. I'd expect to see 120 kW controllers going for around $1000, big motors going for a couple thousand, 20 kWh battery packs for < $5000. So maybe in 10 years we'll have superbike performance at the $15k price point .. but not in 2-3 years.
