according to manual book

 

1st gear = 10.5k rpm

2nd gear = 10.5k rpm

con'd until 6th gear

 

but mine, this is what i did to my bike, as THE DOHC system are build to sustain high rpm without error, compare to SOHC bike system

 

1st gear = 11k rpm

2nd gear = 12.5k rpm

3rd gear = 13k rpm

4th gear = 13k rpm

5th gear 13.5k rpm

6th gear = maintain redline

 

i tested with these rpm, i was able to clock at 170kmh on tangkak highway, my sprocket adjustment was 14-42

 

oh thanks bro, usually i shift up ard 9k-10k+. thanks for the info.

[ashiem]

a standard cbr150r wasnt able to maintain at 13k rpm...stil need to made a few minor modifications...

Hi bro that is really for racer and fuel consumption will be very high. not wise to maintain redline all the way in 6th gear. further more dont forget the power cut that we have in singapore.

since u r taking engine apart enough to access con-rod, why not check for the rest of the components and replace one shot? saves u the hassle of opening up the engine again next time.

 

i did my for about $450. opened engine to replace tensioner guides and got others like piston replaced too.

 

 

hi bros, may i ask what is roughly the ideal rpm u guys shift gears up? i scare i might rev too high for my riding style. (for normal travelling.)

 

IMHO, 9-10k rpm is too high for normal riding.

different pple got different standards for normal riding i guess? hehe

if u r going to whack the bike, just standby more $$ for wear and tear replacement. that's all.

[underage91]

any CBR125 here?

[chipsmore]

oh my haha ok will reduce to around 6-9k then. i nv really see the rpm la i just listen to the sound but usually i shift up quite early i think, on highway i maintain around 7-8k on 90-110km/h its fine right?

[ashiem]

forget something *

 

only when i was in jb haha...ill speed up a lil bit...

 

im into track anyway with this little cbr....

is this correct bro? becoz i read through the manual and it doesnt say to shift gear with this RPM. It just read there when you attain the speed you want then you shift gear.... just askin bros...

yes i do this also... its like punishing your bike when you hit it to 10-11K rpm...

[ashiem]

different people, diff point of view...if u asked me, than thats my best answer anyway....ive been doing that, n lucky, nothing bad have ever happend to me n my bike...

symptoms like jumping of gears after u have engaged gear. e.g. gear jumps from 2nd gear to 1st gear after u have engaged and clutched out.

 

another so called test of worn out clutch plates is when u engage gear 1 from neutral gear, whether does the bike jerk forward. but note that this test may produce wrong result as having improperly adjusted clutch biting point will also result in bike jerking forward.

 

in a very bad case of worn clutch plates, the bike needs to rev higher in order to achieve a certain speed. e.g. before, 90kmph at 6k RPM. after, 90kmph at 8k RPM.

 

based on what u have described abt sudden drop in RPM while maintaining throttle, it seems to me there is a possibility that it could be due to fuel or electrical issues as well. just dont want u to spend money for nothing.

 

thanks for the advice. i'll try to get it checked on my next servicing. btw, which workshop do you guys usually go to for servicing? because i know of some workshops that prefer working on bigger cc bikes and hence give lesser attention to bikes like ours. I usually go to a workshop at somewhere near geylang lorong 25 because the prev owner used to service there . However, its quite a hassle for me because i live somewhere in the west.

well bugsy,

 

I just replaced my clutch plates and clutch springs. got it done for around $80.

sadly, there's not much of reputable motordiam in west side.

in terms of reputation, can try unique at toh guan.

for relatively simple stuff like changing oil i think almost every shop can do it.
