2018 Yamaha YBR 125G Biker Dudes Review?
Well, the so called 'biker dudes' don't ride 125s. Heck, they don't even ride 500s!
They ride 1,600cc - 2,000cc cruisers with a massive 45-Degree American V-Twin; with each piston having a displacement of 800 - 1,000cc.
These things can shake the fillings out of your teeth.
Plus; bikers 'tend' to weigh north of 300lbs / 136KG (As seen in the snapshot below), support KKK, Republican party, Donald Trump, Holocaust, Adolf Hitler, wear Confederate Flag and tend to hate Africans, Asians, Muslims, Jews... Pretty much everyone who isn't a Caucasian with a white skin.

So... Trust me; you don't want to be a 'biker'!
Me and my friends once accidentally ended up in a 'biker bar' in Texas; foolishly thinking it was a 'regular' gas station / petrol pump.
Worst mistake of my life. We were lucky they didn't skin, rape or crucifiy us. And I'm not joking.
I was spat on my face; because of my 'brown' skin whereas a friend of mine was hit with an empty beer bottle and had 6 stitches.
Took our wallets too... We didn't even inform the police because that'd be suicide, plain and simple. They'd our addresses, driving licenses and credit cards.
I hate 'bikers' ever since.
