Alta's 5.8 KWH battery pack
The Redshift owes its speed and endurance to the custom battery pack which powers it all. The Alta Pack crams 5.8 kWh into 30.8 kilos with a maximum of 350V: mile for mile, there is no smaller, more energy dense battery pack in transportation. Our battery team gave themselves three years to develop and commercialize wholly new technologies to achieve the performance and safety we demanded of an off-road race bike. The Alta Pack is waterproof - rated up to IP67. It is durable enough to handle impacts and vibrations up to 20G, and it is digitally self-monitoring. Our stacked, honeycomb architecture allows for extreme energy density at 185 watt hours per kilogram. This paired with a unique thermal wicking system to shed heat faster than any other lithium-ion transportation battery in production, gives the Redshift the edge you want on the track.

The maximum allowed voltage in the main power bus is 400VDC or 285VAC. A
secondary power bus may be used to supply energy to the critical systems at a
maximum voltage of 20VDC or 14VAC.
50.04.3 High voltage symbols
Symbols warning of 'HIGH VOLTAGE' must be displayed on or near the electrical
equipment protective covers; all symbols must comprise a black flash of lightning
inside a yellow triangle with a black border. The sides of the triangle must measure at
least 8 cm, but may be larger if practical.

Lets not repeat the 4 stroke handicap racing saga again.
People assume that we need to know exactly how to make a watch, when all we need to know is what time it is.
They only need to cut their bike prices and it´s gonna be success indeed.
Pit Row
"Have you ever wondered what Supercross riders say to each other after a dirty block pass? With Electric bikes there is a good chance you will hear the conversation. Will the electric generation of racers use trash talk? No more need for pit boards, just yell! The same joy I receive from the smell of 2 Stroke oil or hearing a bike roar will be what the electric generation receives from a buzzing sound similar to an RC car along with the sound of tires spinning. Yes, I said the sound of the tires on the dirt. About 5 minutes into my Redshift ride I stopped and checked to see if I had a flat. Chad at Alta Motors erupted into laughter as almost everyone who rides the bike assumes the same. Dirt Bike tires make a lot of noise, but the motorcycle usually drowns out the sound. Hearing your tires might lead to advancements in tire performance, who knows? "
There is also a link to a full test by Cycle World that is very informative.
I have no problem with putting Alta's in the 450's from the get go. Both classes run the same lap times anyway. When they bust a holey week after week there will be less crying.
It's a tough road to hoe for promoters and organizers who's main goal, at the highest levels, is keeping the manufacturers AND the fans/participants happy at the same time. The problem with manufacturers is they rarely want the same thing as each other, and almost never want what the spectators want. You can't make everyone happy, and so the goal just becomes not to piss everyone off. A no-win proposition if you will.
In the end, when it is all said and done....follow the money...and you'll see the light. It's "professional" title is not status symbol. This is a occupation for every single person involved. Money is the prime motivating factor for any and all of it.
Here is the AMA's position:
"Fled" with the money Circus killers and the big money back room cigar smokers need to realize that it's all about selling seats and TV ads. Having E-bikes in the show would do that in droves based on this forum's interest alone.
If Alta wants some pull, then they need to pay their dues. How much have they contributed to American motocross. How much money do they bring to MX Sports or Feld. How many fans will walk if the walk? Will the sport fail without them? the answer to all those questions is a big fat zero.
.
you say make MX great again with the gusto of a supreme narcissist. Like your idea of "great" MX is anything like mine. I'm not interested in enginecycles, I'm interested in motorcycles. More importantly, I already think MX is great.
Besides, technological innovations are just as good at killing traditions as they are creating them, right? Not everyone is interested in innovation either, or the increasing costs. I could care less if dirtbikes completely stopped evolving. They've been pretty much totally awesome for the past decade, with no real innovations to speak of.
Now I understand that innovations drive new sales, and new sales greatly improve the health and growth for a manufacturer, I just don't think it's necessary. You can go to Italy and by a pair of shoes that was designed 200 years ago. Does that make them outdated, or are they still the sexiest shoes you ever laid eyes on? Is the newest bike you ride, always, without question, the funnest bike you ride? do you know what the most raced car in this country is? its the origianl Mazda Miata. and if I have to explain to you, why that is, then you have no business discussing organized motorsports.
Kind of ironic statement here.
We've all witnessed the cluster fu*k when the powers that be allowed 2&4 stks to race together.
It was unsafe & dangerous, & thank god they saw the light.
Here we go again it seems.
Alta's & the like need a class to themselves.
Time will prove I'm correct.
It's as clear as the nose on 1's face.
The electric power delivery & torque is way to different to be mixed in with fuel bikes.
Again, I'll just sit back & watch what happens.
