What Would it Take to Try for a LSR Electric?

posted in: Racing | 0

Many dream of Bonneville, but few attempt and fewer succeed. But the electric classes are new and many classifications appear to be untried.

At El Mirage, they run a smaller set of classes under the same rules ( almost) as Bonneville. El Mirage is only a three hour drive from Santa Barbara.

The rules are complex, but for E machines they break down into simpler classes. LSR rules have a dual class system: first half for chassis, second half for engine.

For bikes, the chassis classes are:

P Production
M Modified
MPS Modified Partial Streamlining
A Special Construction
APS Special Construction Partial Streamlining
S Streamliner
SC Sidecar
SCS Sidecar Streamliner

For E bikes the engine classes are much simpler:

Weight determines this engine class:
NOTE: Pound weight converted from Kilogram weight to match the FIM regulations for this class.
Weight Class
Maximum weight

  • 150kg (330.7lb)
    300kg (661.4lb)

So the easiest, likely slowest class is P for production and 150 kilos. But production bikes are expensive without a sponsor, so here are some other classes that would make sense for us:

A Special Construction
APS Special Construction Partial Streamlining

An A bike could just be the APS without the fairing.
So if we went for the A-APS we’d need a stretched chassis from a road racer or dirt bike, its good to stretch it out to get more room, and say 100 lb of batts. That ought to get us to 100 mph with ease I’d think.

Here are the national records from AMA and Bubb:

Solar/Electric Weight Classes (W)
150kg (Approximately 330.69 US Pounds)
APS-W 68.848 Ingber, K Electrobike 2007
SC-W 60.583 Carey, G Kawasaki 2010

300kg (Approximately 661.4 US Pounds)
M-W 20.256 DeSimone, H -2005
APS-W 173.36 Thede, P Lightning 2010

Unlimited (301kg and over)
A-W 47.246 DeSimone, H Honda 2007

Practically speaking a 150 kilo limit means you need to start with a roller thats about 200 lbs. That means GP-style bikes TZ250 RS125, and dirt bikes. Dirt bikes are plentiful and cheap, but they have the wrong wheels and brakes, you’ll want standard 17″ rubber like a motard and serious brakes.
