Title: Alta Motors - After a few months of real world testing
Post by: EliteMotorsports on April 29, 2017, 02:45:13 AM
After a few months testing the Alta Motors Redshift MX and running demos with customers here is what I have found:

Average run time during demo runs at the local MX track: 1-2 hours (faster riders will use the battery up quicker than beginner to intermediate riders)
Average run time trail riding (fast rider on technical trails): 2+ hours with more testing coming this summer
Charging time: 4-4.5 hours using the 110v outlet in the shop / 2-2.5 using the 220v generator at the track. The best practice is to plug the Alta into the generator anytime it is sitting still, doing so will allow you to extend your day significantly. We are using a lifan 4250 Platinum generator which is about the bare minimum for the Redshift. Ours required a high altitude jet kit and some airbox mods for charging at 4500-5000 ft.

Maps: Alta has done a great job of making the throttle feel smooth and responsive on the Redshift MX. the Redshift is very easy to ride and feels much like a traditional gas bike once you have wrapped your head around not shifting and using a clutch.

Map 1 - very smooth and easy to use. This map limits wheel spin and will keep the front end on the ground (for the most part). I tend to use this map when riding in tight corners or super dry/dusty conditions where traction is a premium.

Map 2 - This is noticeably more responsive allowing the rider to loft the front wheel over logs, rocks, and other obstacles. Map 2 is likely to be the goto map for those who intend to trail ride the Redshift MX.

Map 3 - This is where most Motocross racers will want to ride the Redshift MX. The power delivery is great for the faster MX tracks and should be the ticket for most riders.

Map 4 - Map 4 doesn't feel a whole lot different from map 3 but does offer up a bit more power. The fastest MX racers might want to run map 4 on the faster tracks.

Suspension: The WP suspension on the Alta Redshift MX comes valved very soft. This would be a great setup for a beginner MX racer or someone who intends to trail ride the Redshift MX. Intermediate to expert MX racers will want to invest in suspension services to make the Alta more competitive on the track.

Power: Alta is marketing the Redshift MX at the 250f market. In use, we found that the torque that the Redshift MX delivers makes it feel like a much bigger bike (think 350f KTM). Everyone that rides the Alta is blown away by the amount of power that the bike has.

Handling: The lack of rotating mass make the Redshift MX feel much more nimble than the 251lbs that are on the spec sheet. The bike is quite nimble and feels more like a lightweight and nimble two-stroke motorcycle.

That is our early test of the Alta Redshift MX. We plan to do more testing and more demos throughout the summer and will keep you posted. If you are interested in riding the Alta feel free to contact us. We are happy to schedule a demo ride and let you test the bike out for yourself.

+1, big time!  I've been waiting for something like this for several months now.

Thanks for the ride up! Have you figured out a more comfortable seat to put on it?  [emoji6]

I am working on getting a comfort seat done by seat concepts :)

Nice write-up Scott. Thank you.

Any experiece with deep water crossings, like at least countershaft sprocket deep?

Hi,
I will let Scott comment from his experience, but it should be no problem since the bike is rated IP67 (30 minutes under 3 feet of water)

I haven't done any deep water crossings personally...I plan to this summer. I have pressure washed the bike after each ride with absolutely no problems though.

Thanks guys.

I am a gearhead through and through, but a complete neophyte with respect to EVs. That IP67 is an interesting specification. Where does one find stuff like that? Would it be in the printed material that comes with the bike, or a detail known to engineers and developers?

Here is the definition of an IP 67 rating:

"Enclosures constructed for either indoor or outdoor use to provide a degree of protection to the personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against hose-directed water and the entry of water during prolonged submersion at a limited depth; and that will be undamaged by the external formation of ice on the enclosure"

6 = Totally protected against dust
7 = Protected against the effects of temporary immersion between 15cm and 1m. Duration of test 30 minutes.

I just had my first trail ride today and managed to run it dead flat in a couple hours.  Thanks for the tip about the lifan, since now I am looking for portable 220 generators.

We are selling the Lifan 4250 generator and replacing it with a bigger Yamaha unit so that we can charge two bikes at the same time. Shoot me a message if you haven't purchased a generator already and I will get you a quote.
