What would you say the best dirt bike brand is and why?

Okay so my favorite was the yz but the bottom ends on the f's seem to be going on a lot of em around. I even rebuilt a 426f from bottom up recently. Seems the cranks are breaking farily easy and there's been a lot of grenading the engines happening with yz. I had the yz250 and a yz100 both were great bikes. 2 stroke. The ttr125L was a fun bike I recently got rid of a ttr230… No kick lever? Cmon! I'm all set with buying battery after battery. So I got a honda xl500r… That bike fun! Developed a tick tho it was old and then the muffler baffle started rattling. It broke. Only way to fix was to cut the muffler on that old bike and reweld. Gasket leak and then the kick lever spring broke. I loved that bike started first kick every time like my old 90 suzuki dr650. (One of the most reliable bikes I've had yet and still have) i have had the drz125 nothing but problems for me… The ktm 350 is a bike I recently got. An 86 kicker on left side. I'm loving this bike! 2 stroke enduro. I had the ts250 too and that was also a fun bike. I've had more but tell me what would you say your favorite brand has been and 2 stroke or 4 and why?

For the money Yamaha has been my brand for years, still own a YZ 450F. Haven't had all the trouble you mentioned but mostly they were reliable for me even though I ride and raced them.

Have raced and ridden a few Eur. Brands, Husky, Sachs, Greeves etc with Husky being the most reliable but parts were expensive.

I have owned four dirt bikes in my life. Three of them were Suzuki. Never had a problem with any of them.
