speed advantage: 110cc manual clutch vs. 125cc full automatic


This is something that has been bothering me.

If you were to go for pure speed, would the bigger- engined full automatic have more top end.......or would the manual hand clutch 110cc have the advantage.

Some people say diferent things so I decided to post this on the forum to see what you guys thought.

how much more hp is the 125 than the 110cc


BEN
thnaks

GOD BLESS

the 110cc manual would get the jump off the line but depending on how far of a straight line race you are talking the 125 will out power the 110cc on the top end but again it all depends on the which China brand motor your talking because they are not all made the same. On a road race course the 125 auto may or may not have the advantage also. All is based on rider experiance not all bike. 80% rider / 20% bike

right.....how would the rider know when to change gears because the tachometers are soo innacurate.??...would it just be on what the pitch of the engine sounds like?

Of coarse the manual is probably a lot more fun

it is true that u have to go off of engine sound and feel..and that stock for stock the 110cc will get the jump off the line...but with some custom springs the 125cc would launch just as hard if not harder and will be more consistant

Yes you would listen to the motor rev or just get an aftermarket tachometer There are alot of variables that can come into play that can change the whole dynamics of the race also. From experiance riding the 110cc manual clutch it is not a joke. I was caught way off guard on how much of a power differance it was to ride the 110cc auto versus the manual. MIDMADNESS let me take his bike for a spin at a local track and I definately had to control my throttle through corners and in the straights his bike pulled hard.

what do you mean by custom springs??

i do know that the guy selling teh 125 auto told me to change the sprocket cause it kills the 1st 2 gears

i would like to teach myself how to use teh clutch to my full advantage......it would help me in the long run, i like the thought of the extra power is nice though

I went to ace hardware and took my stock clutch springs then got a assortment of springs that where stronger..and put in heavier springs and testing them...once i got the best launch i could without wheelieing too hard i stayed there...I also had my clutch redone with kevler by a local motorcycle shop...on a mini tach it showed my clutch engaged at around 2800rpm and it takes all of my 215lbs to keep the bike from blowing over...also have my front lowered and back raised a lil to help this as well

so you were talking about tehclutch springs...ok

yeh i guess that makes sense, but that kinda seems liek a lot of work, but i dunno

it would be sweet to have an auto that popps wheelies when you pin the throttle every time...no leaning back

how mch top end would a stock 125cc have over the 110cc manual version of teh same motor???

just talked to the dealer....he said the 125 auto has at most a 3 mph higher top end than the manual...so not a huge difference there

the manual also doesnt have a rotarty transmission...like the auto..meaning you cant cycle through the gears n,1234n1234 ect

i think its 4 up...then 4 back down
i think this is a good thing..but i'm not sure

GOD BLESS

Try not to believe to much of what the dealers tell you because when it comes to these China bikes it has already been proven nothing is what it seems to be.

chi sox fan- Teh the...i cant stand it ...for some reason the way I type...i always hit the "e" before i hit the "h"....it really ****es me off..sorry

i'm getting the manual clutch because i found a really good price from a guy that I know. I also want to have something more like a reall bike.......i'm used to a full manual anyway with my dirtbike.
I cant find a good priced immortal that is semi auto
The 125cc does not come with a semi auto or full manual model. It is just full auto.....which takes the "real bike" feel striaght out of it, besides hand clutch or just foot shifter will KIll the auto off the line.

Mellocag- hes not exzactly a dealer....he used to be and now hes just sells bikes privately,
but he races his the manual b1
he also sold deadspace01 his sweet bike,which is the coolest bike ever now that he turned it into a kawasaki/ b1 hybrid


BEN- "the the the the the the the"LOL

GOD BLESS

i know i'm jumping around with what bike i'm going to get, but i'm just looking for a good price.......which is why right now i'm almost (almost..hehe ) positive that i'm going with a 110cc immortal full manual (hand clutch) 4 speed.

PBU bikes are SICK.....but they just runn a little tooo much $$$$cash money$$$ for my taste

GOD BLESS

ummmm.....
the stock 110cc engine is 7.5hp
the stock 125cc engine is 12.5hp

it may have the same top end as the 110cc but you'll get there a lot faster.

a 5hp gain is huge on these bikes

I'd rather have Uh-Oh build me an engine for the cost of a 125cc though

the 125 isnt actually that much money..its the same as the 110cc manual

the 110cc stock would get to the top end quicker because it is a fully manual compared to the auto 125cc

i live kinda in the middle of nowhere in a little nieghborhood, i just drive it there.....maybe a little in the street...and i sometimes take it to my friends house to ride and fool around with

it starts...but whenever you rev it high...the engine shakes violently and is second from totally snapping off, so i have not ridden it...i'm probably going to be selling it for parts once i get back from arkansas.

dude..i'mn glad you liek your x12 sounds great...this whole week i'm trying to convince my dad to help me withye the costs of the bike...the i'm going to work for him to pay him back
