My question to you guys is:
1) Would you still buy an ALTA today knowing the big 4 will be coming to market with their versions of the Alta?
Your questions have been answered, and you sound committed to the Alta purchase. I don’t think you’ll regret it.
I bought my 2019 EXR a month prior to knowing Alta was having problems. I was shell shocked (as I’m sure everyone else was) when Alta announced the production shutdown and ultimate closure. But... I also feel it’s one of the best dirt bikes I’ve ever owned, and being an EXR, extremely versatile with no major modifications to “make it street legal”. For single track, turn signals and tail light come off. For daily commuting, lights go back on. I didn’t like swapping tires for pavement use, and I don’t like dual sport tires for single track, so I bought another set of wheels for a KTM and just put a 7mm spacer behind the front brake caliper to account for the offset between the Alta hub and KTM hub rotor offset.
I also “worry” about long term support, but I’ve owned a Buell (bought just before Buell was shuttered) and also a 2014 Ossa Trials bike a year before they stopped production. While it sucks, it never really affected my ability to get parts and long term, other enthusiasts seem to keep supporting the products. I’m stunned I can still acquire pretty much any part I need or want for my 1976 RD 400. Point being, the Alta is a good machine, and I think enough were sold that support will continue at a slightly higher cost than it would be if Alta Motors was still producing motorcycles.
As to chasing your son, it sounds like an ideal bike would be KTM’s Freeride. It was the bike I was intending to buy before I picked the Alta. Problem is, the electric model isn’t sold in the USA anymore, but everyone I know that picked up a 2-t model still loves them. They are also quiet and easier on the trail/environment than a full size dirt bike with aggressive knobbies. I still have an interest in acquiring a used Freeride e version.
