I am not a Lynx expert, but i have owned a few in my youth.
Lynx is developed and manufactured in my neighbour country Finland, first Lynx i ever owned was an model 20 with an 9 hp Ilo engine, drove that from age 4 to 8, manufactured 1967.
The more modern versions, maybe during the 80's they started to use Rotax engines, the only common part with Ski-Doo, Lynx had no affeliate with BRP, yet.
Lynx made awsome work horses with wide track used for hauling timber from the woods, and Snowcross race machines, many european and world championships has been won on Lynx, Pauli Piipola was one of the first and is behind the style of the skid used, that's why it's called Piipola skid.
Janne Tapio another snowcross world champion is still working on Lynx and is head of development (or was a couple of years ago anyways).

The years before BRP bought Lynx BRP put pressure on Rotax and always a new engine model was released Ski-Doo got it first and Lynx had to wait a year or two.
That and financial difficulty finally forced Lynx to join BRP.
I believe all Lynx models is manufactured in Finland still, but most parts are BRP now, except Skid and some styling.
The only model shipped from Finland to US is called Ski-Doo Alpine 3, here it's called Lynx 6900.
