Are you keeping the EXR you just bought?

Do you have the latest firmware? I am also in below freezing temps and just updated my 2017 MX from the original firmware to the newest. Before the update, the yellow light was constantly on when I started riding and it severely limited the power. The new firmware doesn’t show the yellow light...

True 7075 has almost double the yield strength of 6061, but they have almost identical modulus of elasticity (effectively a measure of stiffness), meaning as long as you're not exceeding the yield strength of 6061 (plastically deforming it, aka failing it), there is no benefit in performance for...

That’s interesting, if the A pack is outputting less current than the R pack, why would it overheat earlier? It seems like the construction of the battery pack is roughly the same. Do the A cells not deal with heat as well? Was your 2017 on the latest firmware?

It seems like whenever anyone posts a WTB they specifically ask for a 2018/2019 MXR, and the 2017 MX's are overlooked. Maybe I'm biased because I have a 2017 but I don't really get it unless you are a fast motocross racer and need that bit of extra power. As far as I can tell, they all need...

For anyone planning on using this adapter, I wanted to confirm it does NOT seem to have the ability to load new firmware. Even though I could see all of the data in Multitool, the firmware update would not work (neither the update utility nor the loader tab). As soon as I switched to using a...

After lots of trial and error, I finally got my ancient Windows XP laptop to dual boot into Ubuntu and run multitool. I built a usb to CAN adapter using the info on this thread: Open Source DIY Alta Multitool CAN Bus Adapter and can see a bunch of data, but am not able to load new firmware (I've...

I am not a computer person, but I finally got multitool to work with this adapter after many hours of frustration! Takeaways: -Make sure to use a USB cable that can transmit data - some are only used for charging things and do not transmit data. -Do not update the CANable adapter firmware to...

There are a bunch of interesting little differences: braces that connect to the battery frame are different, no cover for the display, small selector switch on the right side of the deltawing (instead of a key on the left??) and wires running into it from the top.

@AltaWest said they are going to list a couple more new bikes in the coming weeks, and have shipped to Europe: Sold - 2018 MXR Brand New - 5 Miles - Perfect Condition - eBay EV West Auction

No, I don't think it had ever been changed, but I bought the bike used so I'm not positive. It did seem a little sludgy - the magnet bolt had good amount of sludge on it. Should I just drain a little out so the level is visible in the middle of the sight glass? I'm thinking it would be pretty...

I followed the instructions in the manual to drain the gear oil (it dribbled out all over). I leaned the bike both directions and let it sit upright for about an hour, but it made such a mess I’m not really sure how much came out. I’m also doing this in ~25deg weather so the oil moves very slow...

For Sale - 2017 ALTA Redshift MX

I saw this thread and would love to, but I already have plans that weekend.

Well it ended up not mattering... The course was 5.5 miles long. Everyone did a parade lap and then went straight to the starting line. I did 3 laps in a row (because my teammates bike wouldn’t start). I came in with a little less than 1/4 battery remaining after the 4 laps (I rode all in map 1...

I’m racing the 2 person team “Scare Scramble” at Airway X Motocross Park this weekend. I don’t know much about it other than it’s around 3 hours long, a 5 mile lap and you trade off with your teammate every 1-2 laps. I only have a standard charger - will the battery last the whole race if my...

Do you know what plugs to use for the drain and overflow holes when trying to close up an early MX? It looks like the overflow could use a barbed plug of some size, and the drain is maybe a 1/8" NPT?

It looks like the data sheet says that cap normally comes with a flat fiber gasket, but a flat rubber gasket (NBR material) or o-ring can be requested. Maybe the spec changed during production? The dimensions for the flat rubber gasket were listed, so it should be easy to find a replacement...

Here are the pics, let me know if I misunderstood what you were asking for (I’m not sure how to rotate them from my phone)
