We simply can't know. It also depends on the throttle abuse ;) and oil change interval. Do oil change every 5-6000km when the engine and oil is still hot! (metal oil container)
Is there a possibility to install an aftermarket central stand? This is a way to big and heavy bike just to keep it on side stand, especialy on off-road.
They added bobbins (or what they are called) on the rear axle to easily lift with those simple lifters (with the small wheels on them). And I guess there will be center stand on aliexpress pretty soon.
ps: this bike is not for off-road. A little gravel yess, but it doesn't have the suspension travel, doesn't have the front 21" wheel and it is heavy as an elephant. Also the inner front diameter is 41mm - other manufacturers start at 43mm.
