Apparently West London Yamaha have pioneered a way to "de-restrict" the YZF R125, and are charging £150+vat to do it.

It consists of fitting a specially modified secret part and a new sprocket,

Now common theory is the bike is not restricted any way, so firstly I imagine this is tuning.

The second thing is there is supposed to be an article by Liam from MCN floating around somewhere, where he had the work done...
I cant find this and wanna see what he had to say.

I just dont seem entirely convinced, expecially as they claim that you dont need any kind of fuel management system fitting.
Can anyone shed any light on this as I am having real trouble finding anything out!

Thanks

right then, the bike is resricted from word go. to derescrict the bike you do not do anything with the rear spocket or the front, all this will do is change the accelaration.

the bike is resricted in the exhuast pipe, if you knock the baffels out it will be abit quicker and loader. or you could do it properly by buyin a chip for £5.00 off yamamha with cancles out the rev clock and will allow to rev way past 12rmp. but a full scoirpan or lavinchy pipe, ur bike will then be de-restricted..... the best thing to do would be wait till new year now if you havnt allready done anything about it, i say this because mosati have made a 192cc big bore for this modle of bike with a pipe and crank shaft to match in suit.

do not do anything with the spocket
