Which one revs faster - the TB117?

What are the approximate HP and torque specs of these engines?

TB parts are about equal to yx parts huh?

you can make either of them rev like hell just depends on the rotor. you can get an inner rotor for each which make em scream on teh rev limiter alot or you can get a lightened fly wheel which isnt as bad. both are good choices though. i personally run the irk

I have both TB117 and YX150. I have the 25/23 head from Dratv on the 117 tho, ported by AHP. Motor rips for sure but It's not near as quick as the YX150 in my SSR. I have flywheels on both motors and the YX revs a lot quicker and pulls for a lot longer. TB stuff isn't the greatest quality but neither is the YX....

just ride and have fun....most of the speed comes from how long you keep it pinned anyways...in MX that is.....but I say the bigger the better when comparing to TB engines....now +R engines theres no question...just alot of money involved.....

yx150. throw on the v2 head and the 170 bigbore kit. youll murder the 117. MURDER.

I would decide between the lifan 150 or tb117.

how can he murder the 117 when the clutch basket disentigrated and bust the cases on that yx v2 head.

Depends who's riding the bike

i had a 117 for vegas two years ago. It was a much more mild set up than what you can buy, really fun motor and still could sing it out. What im getting at is the one you could get is gonna be a impressive motor and to boot honda so to speak. Ive ridden the 150 in a 10 inch set up and personally i found it was much harder to ride. Might of been the chassie it was that didnt help. But in short, when my twin bro was on that at moto town and i was on my 88 i could keep up with him. Keep in mind both of us for the past two years have been keeping the 1 and two spots in all of the 88 classes and took the championship in the the 10 inch rock star class so you do not get much closer for evenly matched riders. In short that yx had 4 total rides on it (no racing) and the cam blew to pices causing two brake both rocker arms and send the ball bearings through the head. Now that motor is sitting on a bench in my basment collecting dust.

Keep in mind the yx does have a 4th gear so that is where your buddys will get you is on the straights.

If id had to pick id still go with the 117.

mr.699

get the yx motor with a 165 v2 with 28carb and you will be good

until the crank breaks. or cam. i hear crappy things about that motor breaking

he should get my 117, its wayy more reliable and its really fast (way faster than a normal tb 117) it hangs with 124s!!

I really do like the 117 i'm just broke as a joke

ChainReactionR1

better to be broke with a Honda, then broke with a broken china motor

50ryder420

lol

iskatealot33

if we still had signatures that would be mine

Well Get the tb117 if you can throw that dough down, but if not get the lifan 150.

I have ridden both and i have a yx150 motor in an ogm i have. I personally dont lik ethe yx150, its not smooth power at all. Feels like all grunt. The tb117 to me was a absolute blast, If you are riding for fun i would go with the 117, if you are riding to race i would go with the yx150.

SCAR8

Yea it really does depend on what your riding style is and if your racing etc. 117 is a blast to race or just play on. It's a good motor to hold WFO on the ragged edge all the time. I wouldn't won't to do that on the YX150 for fear it would fly apart. I did hit some really high revs on my YX yesterday on the big bike track tho. Can't wait to see whats in the oil. hahahaha
