    Got myself a practice bike

    Well... I got my CRF450 Showa suspension back from the tuner. Went to a far away track today, which is a bit choppy and tacky. I took the Honda and my two Altas with me. Started the day with the Honda because I was anxious to once again experience the hopefully still awesome suspension that I...

    Getting used to this no-clutch thing!

    Thank you for the video. You should change the view to the wide setting, else the camera seems too low to show what's ahead and too high to show the bike.

    Dyno comparison Alta Vs two stroke and four stroke

    If you add other gears, then the HP chart will gain other blips of the same height but at different speeds, proportionate to the gear ratios. No surprises there, you can visualize it pretty closely without plotting. On the Torque chart the blips will be higher at lower speeds and lower at...

    Swapping MXR/EXR front suspension

    I think it is a direct swap. However, the EXR fork will feel too soft on the MXR, so you'd either have to respring/revalve it or swap the rear shocks as well.

    Dyno comparison Alta Vs two stroke and four stroke

    What kind of a dyno is this (type, brand)? If you can simulate any load, then you can record 1 run 0-60mph with the regular 400 lbs load (bike plus rider) and then another run with like 600 or 800 lbs load to simulate an uphill. The run with a heavier load will take much longer, so it would be...

    Dyno comparison Alta Vs two stroke and four stroke

    So, according to these charts, the 250's do not stand a chance. I have some 450's charts in my dyno thread. They too need to be revved and shifted at high RPM to keep up with the MXR. One question remains: Does Alta reduce the power after the throttle is held at WOT for X number of seconds...

    Bike Ramps and other loading tips

    What? You look like a millennial to me here. You may have to hit the gym, but you should be able to load bikes without any ramps! :D

    Bike Ramps and other loading tips

    I never owned a truck. First, I had a sedan with a bike trailer, then a Ram B-van, then a Honda Element (one bike fits inside, and the other on a bike trailer behind!). But a few years ago I was in Arizona with a dirt bike but without any of my personal vehicles. I rented a Ram 1500 truck. That...

    Is the bike landing any quieter with your new stiff fender bracket?

    Long Term Alta Ownership Considerations

    I wouldn't worry much about it. Electric motorcycles are, just like other vehicles and electronics, are consumables. With a normal and regular use the Alta should last you at least 10 years. They haven't been breaking all that much, so it seems that this forecast is very realistic. As they...

    Alta "Factory" Rider Dream

    Sponsoring a rider takes money. I am not sure how much. From my last year's experience collecting money from the Forum to save/buy Alta Motors, I am not optimistic that we can pull it off. Feel free to give it a try. I can help, but I am not going to be taking the lead here, sorry.

    Rediscover this day: It's been 3 years!

    Google just reminded me this morning about something very important. Three years ago today was the first time I swang my leg over an Alta Redshift MX! February 11, 2017 there was an Alta Demo Day at the Hollister Hills SVRA in the Northern California. I drove over there, but instead of riding...

    Alta "Factory" Rider Dream

    The real Alta Factory racing team tried to enter Supercross and Arenacross two years ago with no luck. They couldn't get in. They were only allowed to run in Endurocross.

    Electric Flat Track at The One Moto Show in Portland - Feb 8

    Congrats! This is a great showing! What is the weight of this tubeframe Alta flat tracker? I am curious whether it is significantly lighter.

    Uploading SM maps to the EX?

    Would uploading the SM maps into the MXR reduce the power output to 40hp? @OneLapper uploaded the MXR Erzberg maps onto his MX and thought he got more power in Map 4. So I am wondering I would lose the top power if I upload the SM maps into my MXR.

    Electric clutch

    I just made it up. The 504 battery cells should be good for about 150 hp. I am not sure what the limiting factor would be for the rest of the system, other than the heat.

    Electric clutch

    The motor current sensor that you showed us?? Or the firmware, if it ever gets cracked.

    Electric clutch

    Would adding a simple throttle kill switch to your LHRB lever work for you and solve all your problems?
