Anyone had any input on the 2019 zforce 800. Doing some research on them and any feedback would be appreciated. Heard about some airbox issues and thermostat issues. So I was kinda wanting to see if anything had been done about this yet or any fixes have been applied to the bike

[2015 Z Force 800 53/Trail EPS]

All the ZForce 800s are almost all the same from 2014-2019 with minor changes and upgrades. The 19s have better brakes, better grade electronics including the thermoswitch and better water pump seals. They also all come with PS and the new half doors. The rest is about the same except I think in Canada they don't put roofs on them and in the US...well ..there are some extras they some get and some don't.

Up to '17 inclusive the Z force E brake is an entirely separate disk brake located on the rear driveline, while the '18 and later the E brake handle just engages the regular service brakes on the back.
The 19 have the half doors whereas I had to buy mine for my 17.
The Canadian models have turn signals and horn but no roof, and they have the huge warranty but at the amount they cost you could say that they have a 5 year extended warranty as standard equipment, no opting out.
