Yamaha BWS 50 70cc Big Bore Scooter Review

Hello Viewers! This is a newer type of video that we are making. Nope its no pocket bike… its a scooter. This is a Yamaha BWS50 and we have big bored it to a 70cc, custom exhaust for increased power, aftermarket air filter, headlight mod so that both turn on in low beam mode, also replaced the battery. Tops out at around 70-80km/h. Really sweet bike faster than a 49cc ruckus. It is a 2 stroke and has pretty amazing torque! Like if you enjoyed and Subscribe if you want to see more!

What kind of exhaust is that? Never saw it before! I’m more familiar with the leo vince expansion pipes

PocketMotors says:

You could probably do what I did for under 500

How much money did you spent? I would like to buy the big bored 70cc too.

Sorry for this, I know it’ll be a very noobish question.

I am getting a 2014 model, Yamaha BWS 50cc, and I’ve been looking everywhere for a Big Bore Kit but I can’t seem to find it ANYWHERE. I know you’ll give me a very obvious place to find it, but where did you get yours from??

Hey nice setup. I just got my BWS 50  yesterday and I did the dual light modification today. I am considering doing the 70cc upgrade but I was advised by the dealer not to as it decreases the reliability. I would appreciate any input from you with regards to that statement. I kinda get the feeling that’s what any dealer would say for liability reasons but I thought I would ask.

Vaporz Od says:

that ncy exhaust is garbage. did you rejet your carb after the bbk install?

CoDy King says:

man thats so sick!!!!! i got the same one but not souped yet xD

Thezubzist says:

if that scooter does only 75-80 with a 70cc kit, then you should get an new exhaust because it may be strickted 😉
