    Media Review AJ Catanzaro - Best bike I have ever ridden 9.9/10

    It is strange that AJ got arm pump. Shouldn't he be riding one-handed??? :ROFLMAO:

    Battery is dying so fast...

    I used to ride four 10-minute sessions at my local MX tracks on each of my two Altas. Recently, it has been only three sessions on each. I like to tell myself that these are not the batteries getting a shorter range but me becoming faster. In my defense, I noticed that I keep the throttle pinned...

    Wing Seats

    I went to my third AJ Catanzaro class a couple of weeks ago at Cahuilla Creek Raceway in SoCal. We had another one-handed riding session, which was cool. AJ says that if you are having difficulty riding one-handed, you are doing something wrong. He claims he can jump any jump one-handed. You...

    Battery Build

    Yes, for the DIY market cost is also a big factor. That's not necessarily true. You can keep the BMS hooked up to the battery at all times but use it for charging only. This way you will retain all the battery monitoring and balancing. In fact, you can have the BMS power not the motor but just...

    EM Factor-E Trials: 4-speed transmission, Flywheel, and Clutch

    Things like that happen very-very rarely. This year we are extremely lucky to have three established motorcycle manufacturers who decided to venture into the motocross market: Beta, Triumph, and Ducati. I do not remember this happening before in my lifetime. Motocross is prospering! New...

    AJ Catanzaro rides the Stark Varg

    It is interesting how he completes the corner while standing up but then sits down for ~0.8 seconds in order to accelerate. Then he lets the bike kick him up to stand up again. He wheelies through almost half of the straight! He pumps his legs while wheelying in order to maintain the wheelie...

    Battery Build

    That's what @DonCox does. I am thinking, without more sophisticated electronics than a simple BMS, it is safer to let the battery drain low and feel the gradual reduction of power rather than let the BMS kill your bike completely (or partially in case of multiple BMS/batteries). A typical BMS...

    MX14 80/120-19

    I have one of these, waiting to be installed when there is a need for it. On the Alta, the tire-fender clearance has been an issue with most rear tires. I run my rear wheel closer to the back end of the swing arm slot. Let me know how it works on the Varg!

    General Dirt bikes are horribly inefficient

    You could probably buy/rent one of those Boston Dynamics dogs and test what their off-road riding range is compared to the Alta/Stark. But for ultimate efficiency, nothing would beat a horse or a mule. Just feed them grass and water. Renewable flex fuel.

    Varg charging from generator.

    You'd need a bigger ~4,000W generator because the Varg likes 220V at 16A. Then it would work.
