My tests indicate that your theory is probably correct, i.e. if you don't turn the key off, the system is calculating energy consumed by summing the volts*amps*dt and using this as the energy state displayed and also to decide when the battery pack enters blink mode. If the key is turned off it...

Energy is definitely not "created or destroyed" by playing with the key in these tests. What is at stake is how much energy the computer thinks is available and will therefore allow you to access. So far, my one test indicates that you have access to more of the battery's energy if you don't...

I've done two rides with the Renthal O-ring chain and noticed no adverse affect on range or power delivery. Like Phillip says, the bike is noticeably quieter and the chain isn't flimsy like the stock chain. I like it! Steve

Today I rode a full charge without turning off the key and I went 10% further than a similar ride yesterday, ending with the same charge state in both cases. It's only one data point but it seems to indicate that you shouldn't turn the key off during a ride if you want maximum range. Of course...

Here's an explanation that covers the factors you mentioned and also describes the state of charge "learning" function which is based on unloaded cell voltage, similar to what I'm guessing is going on when the power is reset. They mention a 4 hour "rest" period to get an accurate reading from...

My theory is that each time you cycle the main power, the energy reading resets to the value calculated from the zero load battery pack voltage. From what I've seen there is roughly a 10% energy error over a complete discharge cycle so you might gain 10% by not turning it off. I think after a...

I noticed that the battery energy state has a "hysteresis" behavior if you power cycle the bike while charging or discharging (i.e. riding.) This video shows examples of how you will "gain" energy when charging just by turning the key on/off and similarly you will "lose" energy if you do the...

I purchased this one and then took out some links to get the correct length: Pro Taper 520 XRC Chain | MotoSport *Edited for correct O-ring chain, original link was incorrect!* I noticed it was quieter than the stock chain when I took it up to 60 mph on the street. I couldn't tell any loss of...

I've made more mod's and will be doing another review soon. The short list is: 1) 18" rear wheel with high profile tire (Dunlop MX52 Geomax 110/100x18) 2) 12/14 gearing 3) O-ring Chain 4)Trail Tech Endurance 2 ride computer installed to get correct mileage (see my other thread on Alta's motor...

I installed a Trail Tech Endurance 2 ride computer and tested it on the street. With a claibrated front wheel size it reads roughly 10% faster than the Alta computer with the current gearing and rear wheel I'm running. I cut into the foam housing for the Alta computer and installed the...

My friends and I finished second place at this event in 2010 with our homemade e-moto, a converted CR 125 that we ran with dirt or super motor set up. The peak power output was about 20HP but was enough to beat everyone except for one factory bike 8 years ago. Things have certainly changed...

I met with the founders of Alta around 2008 when they saw this video on YouTube. I encouraged them not to make the mistake Zero had made at that time, which was to build a glorified electric mountain bike rather than a full-on electric dirt bike. There was no disagreement between us on that...

My friends and I converted a CR 125 to electric power in 2008 and even that bike had a functioning ride computer! :) The bike cost $6000 total to make and although it had less than 1/2 the power of an MXR it worked reasonably well as an electric off-road bike.

The microphone in this camera is not very good. If you listen carefully you will hear it, but the sound recording quality sucks on the Fly 360 4K. Steve

I'm using a Fly 360 4K camera on a homemade mount. The mount is taped to the fender and number plate with duct tape and has never come loose. Thanks, Steve

The industry standard (KTM, Beta, Husky, Honda, Yamaha ....) is a front wheel sensor for obvious reasons. Cheap doesn't cut it for me on a $10K+ motorcycle, it's the attention to detail and a device that is at least nominally accurate that makes the difference. The Trail Tech is a $90 upgrade...

Maybe this has been mentioned before, but I just discovered that my MXR distance and speed readings are coming from the motor shaft and not the front wheel. This means the readings are WRONG if you change sprocket size, tire size, or let the rear wheel spin. I'm installing a Trail Tech Endurance...

Testing a new final drive gear ratio on the Alta and an 18" rear wheel with a 110/100/18 tire: The taller gearing helped with wheel spin and engine braking but it cut down on the acceleration. I've changed it back to a slightly taller gearing (7% instead of 19% taller.) I discovered that...

I spent several hours tuning the suspension (front and back) to address this issue with little success. What I show in the video is my final set-up. Compared to stock the suspension my set-up is somewhat softer but the rear wheel hop persists. My other dirt bikes behave similarly but with...

The Beta 300 is one of my all time favorite motorcycles. The power delivery is perfect for cross-country style riding, very linear with just a bit of "hit". It has an electric start and oil injection (no pre-mix needed.) It uses a standard crburetor so there will never be a fuel injection system...
