We've been very spoiled lately. Polaris has kept pushing with their own innovation but brought zero news to 2024.
Cat did very little for innovation and advancement until the much over due Catalyst. Yamaha gave up.
After a bad snow year I don't think we could blame Doo for taking their foot off the pedal but I also think they'll keep the snowball rolling one way or another.
Off the top of my head, trail market has seen consistent improvements/additions since the birth of the G4 but really since the Rev Doo has been great with yearly advancements and avoiding the BNG years.
