how can i de-restrict a honda cbr 125r?

hiya, my bike is a HONDA CBR 125 R, i bought it whilst on a cbt learner legal so the bike was restricted, but now i have a full licence so i'd be able to ride any size bike i wanted, i want to stick with this bike and would like it un restricted as i am able to use the extra power, can you please tell me how to derestrict the bike please, thanks

put a 170 kit in it, my lad is 16 stone and it will pull 85 all day and rev out in top 92mph make all the 125 4 stroke look slow

stub, May 2014

Cant derestrict a four stroke 125 there is no restrictors ive got a2013 cbr125 repsol it does 81 down hill in 6,
Ive changed sprockets remaped and put an arrow exhaust this only got me 83 downhill!
Waste of money!
Custom gearbox and ported head is the way forward.

Let a Malaysian mechanic work on it. Seriously, they're fantastic with little bikes.

a deecent service will get you the extra speed imo, after changing the wheel bearings and making damn sure everything is lubed up with the right liquids I got an extra 12mph out of mine, oh and a cheap way for more speed is to remove the mirrors, those things cause a lot of drag so removing them shoud give you an extra 5mph or so, also tyre pressure's help a lot, as for mods I went for a 14t front sprocket, 17t is just silly as the engine doesnt have enough power to drive it to top speed, hope this helps.

dave, October 2010

you can also remove the inlet valve washer put a performance induction kit on it 17 tooth sprocket on the front and a 46 on the back smash through the baffleing in the end can and more ive only done this and i can get 110mph out of my cbr 125 but hitting the rev limita

A 125 will never be fast. If you've got.a big bike license get a big bike. My ZZR1100 does 72 in 1st.

Steve, July 2010

I have a standard 55 plate cbr125 and i got mine upto 85mph the other day if its warm and you keep it pinned in 5th but i would recomend this. My mate put a scorpion can on his and he couldn't get much more than 80mph think it depends on the bike but i would love to get it upto 100mph.

badboy_asbo, July 2010

for joyce my cbr 125 rw7 08 plate i have just recently baught an arrow exhaust full system for it with removal baffle and was the best money ever spent the price for them are 279.99 my cbr used to do 70 no problem at all now it does 90mph no problem at all but i had to put a k&n air filter on to they are £30 well worth the money and F.Y.I remove the baffle out of the exhaust sound really nice and helps them to breathe better

nathan, May 2010

sell it and buy an imported cbr 150 dohc because they are registered as a 125, they do about 100mph and if that still isnt fast enough get it remapped or just get your cbr remapped anyway

mgp, April 2010

you cannot derestrict them unless they have a throttle stop or down jetted carbs.

vinnie, April 2010

hi ive got a stanterd cbr125 it hits 97mph but i carnt seem to get any performance parts it still not fast enough does any 1 no of any where i can get these parts from

i am looking for a race cdi unit for my cbr 125 04.

i have done work to the bike all ready and i need this for the extra edge

please get in touch if you know any sites that i can buy one off.

K.I.A, December 2009

where do u get the sproket from to do this thanks

barry, July 2009

it only cost £2.60 to make this bike do 90 mph you will need a 17 sprocket for the frount i done it and my bike will now do 100mph with K&N + scorpion end can

alan, May 2009

hi danny i just bought a new cbr 125 off ls imports ,
they cell full power cdi units for £25 ,
this is there number 07831 145678 any bike shop will fit for about £45

chris, April 2009

i can tell you instead of getting it de-restricted you can get it race tuned the same as racing bikes get. i had that done to my Honda CBR 125 R, and it hits about 100mph now. although its a very light bike and i dare not go that fast again. Race tuning costs around about £500 average.
Good luck and let me know your thoughts.

My$T3rY, October 2008

where can i get an unlimited cdi unit from

danny, August 2008

i bought a new 2007 honda cbr 125. but it struggles to do 70. it will hold back in power, and wont go any faster. so yr ans i read, if i do that will it cure the problem. and roughly all in, what price would you be talking.

downeyallya@ol.com, April 2007

there is no set restrictor to take out it is just made to go the speed it does,the only way to gain power from it is to fit a big bore kit fit an aftermarket exhaust system and get an unlimited cdi unit and change the gearing by changing the sprockets i.e bigger front sprocket,it can go from 60 mph up to around 90mph so its worth doing it but it all costs money !
