Hey dude I hope u know that yz125 is an enduro dirtbike so try not to break the suspension at the dirtbike track, jumping hills and stuff.

Daniel Reyes says:

I was wondering if the yz125 is a good starter “dirtbike” because I ride quads but never a dirtbike?

Ian Liette says:

I was thinking of getting one of these I am 15and 5″2

Levente Karsai says:

The power is nothing, compared to Ktm Sx

Dave White says:

never seen an idiot double throttle in almost every corner.. raced for 11 years 125 and 250 … sure you ride very good but why even let off and do this double throttle bullshit??? makes no sense and your letting off at critical times..

michael toledo says:

itsLucas says:

how much are these?

Aint1S says:

That PRO CIRCUIT pipe really pushed the looks of the bike over the top!
I was thinking that the pipe has a sort of satin, light brushed finish. That said, I’m going to do that on one of my next bikes! Thinking a good 320 grit paper to lightly brush in the lines will be enough to get it there. Then pass over that with a higher grit 1k+ to knock down the peaks to prevent any dirt from sticking.

stihlms says:

who’s the 16 faggots that disliked this video?

JaxHD says:

or just buy a stock ktm 125 and it will be just as fast or faster lighter barely ever breaks THE BEST BRAKES and then with the extra money just fucking spoil yourself with all the gear you could want and a nice pipe

Antonio Riccioli says:

you can spend whatever you want, the engine won’t get better than a stock ktm one.

56-B52c42o says:

My bike in a month or two

chritopher Rogers says:

I haven’t been on a 125 yet but I’ve been on a 100 and my 250 4stroke, now I hear that the 125 will blow my 250 out of the water. I do believe this because I have a friend I ride with who has one but something I don’t know is why does the 100 feel so much slower than the 125?

Clutch_Luck says:

Rich bastard.. I’m not jealous..

Mark Lowe says:

Totally get why you built this. Nice work. Agree with every word.

wheels ontario says:

144cc kit + hinson clutch = faster bike then this for $1500 not 6g

Danny Ray says:

fuckin dumbass

Fambo Prod says:

I’m 12, 115 pounds, 5’8. I’m a beginner. What would be a good bike for me. Budget $5000

Shaye fiske says:
