Its possible, but i wouldent take it as fact that your cdi must be changed without first getting it confirmed by someone who knows about NSR's from whatever country that your bike was originally for, as its an expensive part to replace, especially if it turns out that it is not the restriction, to your bike. I would firstly check for the usual restriction methods first, before looking for anything more sinister, or complex.
Other ways that a bike may be restricted are simple things like limiting the travel of the throttle slide, or fitting a smaller intake tube to the airbox. and rejetting. Its possible to restrict a bike electronically, but less likely as its a more costly option. Disconnected, or sleeping powervalves can also be a way of restricting the power. The latest yamaha DT/TDR models have the YPVS that was ommited on early models, but they have the cables set up, and a plastic spacer that limits the movement of the YPVS valve, but electronically there is no restriction. Of course its possible that a motor could be restricted all over the place, and made near impossible to fully de restrict, but that very unlikely, these days, as the 125 market is much smaller than before. The old Kawasaki AR125 is a gd example, where they did 2 distinct versions, the Unrestricted A model, and the 12hp B version. The B model had lots of changes, and the carb size was different, as was the disc valve, and the cylinder porting, and compression ratio, as well as an exhaust restrictor, as they catered for both full license holders as well as learners, by having the 2 models. I think that some Euro countries allow 125's to be ridden by 16 yr olds, but with an 80kmh limit, so many bikes have gearing changes as well. Check all the obvious things first, and then if needed, get some advice from someone in the know, but dont listen to silly muppets that just go round saying cut the so and so wire, and whey hey you have a 110mph bike, unless they can explain what is what, as there are plenty of bullshitters out there with nothing else better to do.

oh, and when you bought it did the shop fit a new speedo in mph than km or did they stick some snide stickers around the clock. is it legal to ride like this or is it expensive to get a new speedo fitted?

those sticker overlays make it legal, and it will still pass an MOT. getting a new speedo will be 60-100 quid, and not worth it.

much cheaper
