    Livewire is going public. Alta DNA now with 21700 batteries

    Great photographer, found a view angle that is better than what 3D renderings have been showing.

    MXR Spring weight and Sag

    You'd gain a negligible amount of low-speed torque. The stock MXR gearing is 12/53, but many run 14/53 or 13/53. And I run 12/45. By going with taller gearing, you are losing low-end torque but gaining torque and power at speeds above 35mph. See the magic explained in the charts in the thread...

    MXR Spring weight and Sag

    This is all incorrect. RaceTech is notoriously clueless about N/mm and kg/mm. The stock MXR rear spring rate is 60 N/mm (6.1 kg/mm), and it should be pretty good for your weight and skill level. Also, many Alta riders have found that smaller race sags work better.

    MXR Spring weight and Sag

    You can also keep your chain, re-install the stock 12-tooth front sprocket, and buy a new 49-tooth rear sprocket. This will move the rear wheel back by 1 chain link. The new 12/49 ratio will be almost the same as your current 13/53 ratio.

    2018 MXR Suspension

    The forks on my Precision Concepts revalved bike are on the second line. The forks on my KTM World revalved bike are flush. I haven't experimented with the fork height much. The rear ride sag is 90mm on both bikes. I have experimented with sag and found 90mm to be a good number on hardpack...

    Upgrade C4S to AER's - Possible?

    Yes. If Liquid doesn't have them, then you can buy KTM/Husky/GasGas axle, spacers, and also triple clamps.

    Sounds great, but where are they going to find an equal number of women for all the teams?

    Ktm freeride questions

    The Freeride has just 20hp (right??) It is like an 80cc equivalent. It doesn't have the suspension travel or probably even the frame strength to jump 80 ft jumps. I wouldn't risk it.

    Alta Test Track Build (In progress)

    Heavy equipment noise means someone is working. But noisy dirt bikes means someone is having too much fun, which is obviously completely unacceptable! 😤

    General Do you miss using a clutch?

    So it's the gas cars that are actually slower and they also try to cheat.

    General Do you miss using a clutch?

    Full power -- no, and you do not want it! Full torque -- yes, you can get it. But that torque is limited by the (adjustable) traction control, which is what you also want to have on an electric bike. Else it will be just a drift/loop-out monster.

    General Do you miss using a clutch?

    Ah, okay. I remember reading about the 1-foot "rollout” in Road & Track. This applies to both gas and electric vehicles. Just a silly drag racing math. The EVs do not have any inherent advantages or disadvantages here.

    General Do you miss using a clutch?

    I am not sure what you mean here. Tesla and other EVs (the Alta Redshift) can theoretically give you the full horsepower at zero speed. But that would be an infinite torque at zero speed. The bike will be rideable. You will either spin up the tire or instantly loop out. EV DIYourselfers know...

    General Do you miss using a clutch?

    Almost forgot! Having no clutch in the mud is an absolute godsend! Last time I had to ride my Alta on a muddy track I enjoyed it like a kid, hahaha! The Alta's maps are not good for the loose and fluffy sand. Too much wheelspin. A heavy sand is fine. But with more traction control options...

    TCMB371 Video Thread

    The "light feel" of a bike (and a car too), besides the obvious weight of the vehicle, also largely depends on the stiffness of the suspension springs and the tuning of the dampers. The softer the springs, the less compression damping, the more rebound damping -- the heavier the bike will feel...
