I bought an EXR a few months ago and use it as a commuter. Riding the EXR is the most fun I've had riding in a long time.
But, I really want to get an MXR for MX and Trail Riding.
FYI: I love the forum and really respect everyone's opinion.
I want to get an MXR to do some serious trail riding and maybe an MX race or two.
But it's another 10 grand to spend on a bike that may only last a few days, a few weeks, or never have an issue.
High Risk / High Reward
If it was your money, what would you do?
Simple answer: get one. I had a chance to ride the streets of San Francisco in 2017 while visiting my daughter who worked for Alta. I swore then I'd get one if I had a chance. Last year I got a EXR thinking I would put street tires on it. I'd had 0 experience off road but living in the mountains of east Tennessee made that easy to change. And Brother, it's about the most fun one can have out of bed. Aside from the fact that everyone wants to talk to you ( the "Oh Wow" factor isn't going to end anytime soon.), I'm the only one of my new friends that hasn't spent a lot of time pushing a bike out of the woods or doing trail side repairs. Short of chain and tires, there's just not much to go wrong. I did spend a half hour waiting for the electronics to let me restart after going head first into a mud hole once.
I thought it would be a good learner bike since there isnt a clutch and no hillside kick starting but this isnt a beginner bike. It's like starting driving school with a 911 GTS. Though not heavier than a 450 it's quite a bit heavier and taller than a 250. Picking it up on a hill is rough.
One of the safeguards against whiskey throttle on a gas bike is the clutch. So the no clutch advantage has a bit of a double edge. Most of my serious "dismounts" have been the result of not getting off the throttle or giving too much due to bumps and inexperienced rider panic. If you come down on the rear tire with an open throttle, that bike is going to go into orbit and it will be in post game reflection that you figure out what happened. My solution to this was to get a left hand rear brake lever.
Another other big difference is the engine braking on the ALTA. It's very tricky to keep the neutral throttle spot between no throttle and forward motion. The engine braking is much stronger than a gas bike in gear. It really changes the dynamics on all terrain conditions.
I also love the ability to control the torque in tricky situations such as restarting on a hill. Where gas bikes often have to retreat for momentum, the Alta can control the start enough to avoid spinning out.
A tugger strap should be standard issue. And the headlight is bright enough to read by but not enough to drive. I screwed the headlight adjustment down enough so that I could use the high beam to drive by.
In terms of the rapid battery drain with high rev use, that's more of a pro problem. I usually finish a 2 or 3 hour ride with 20 to 30 % battery. Granted, I'm riding on trails not easy dirt roads and the speeds are less than 25mph.
I love this bike. I would certainly buy it again despite the absence of factory support. I take it as a clue that when ALTA had to close, most of the employees that didn't already own one found a way to get one. That's an endorsement.
