Urgh I've read about that "derestriction" on that hell hole of a forum 125 sportsbikes. Until I see a significant power gain that isn't down to changing the gearing I'm staying skeptical :rolleyes:

wht is the derestriction then?

You've not read much then, except abuse from the 2 strokers. None of them actually know anything about it. It has nothing to do with the gearing either. The only two people that know about the deresriction properly, is myself and Liam from MCN.

an article will be going up on www.onetwofives.com/forums when it officially launches on 1st Jan. Will have a fair bit of info about it and where it can be done.

Imanupstart, having seen a bike de-restricted, i can tell you right now you'd be 110% impressed.

I've read all there was to read on the 125 sportsbikes forum, granted its not alot as its being kept hush hush. I'm not trying to give you abuse like the rs owners do, just saying that until I see it, I'm staying skeptical. :) Have fav'd your forum so let us know when its up, really interested in the results!

Hi,

Well I can tell you that Liam from MCN had it set for a much better performance, power / acceleration wise rather than top end. Sadly, you can't seem to have both a better top end aswell as acceleration.

Top end should see you for another 10mph or so, maybe a bit more. However, it takes ages to get there and in my opinion isn't worth it seeing as it's a 125, so you don't get many roads to get it that fast.

However, if it's setup for better lower grunt, the bike WILL now pull in all gears (Ever faced a hill on an R125? Then you'll know how it hates them!!!!). With the modification, it will now pull even up steep hills. You can now comfortably overtake where as before you just didn't have the confidence in the bike delivering the power quick enough.

Also, the bike will now wheelspin (if that's your cup of tea). Best of all, it won't void your warranty as it's using Yamaha parts! :)

The results are impressive, especially if you have an aftermarket pipe, with the Leo vince showing the most impressive gains from those tested. Also, i'd strongly advise the double bubble screen. it's good for an extra 5mph extra at least, and makes busy dual carriageway rides less nerving (I found with the standard screen, unless I was fully tucked in that the air was so turbulent over 60mph that I lost confidence in the bike as it was terribly twitchy!)

sign up over at OneTwoFives. It has a dedicated section for R125's and i'm hoping it will become a good community. It's far less hostile than 125ccsportsbikes.

I'll give you more info very soon, as im due to get it carried out on my own bike in the first few days of January.

Merry Christmas guys :)

Gents,

Just wanted to let you know that there is now a full review of the Yamaha R-125 De-restriction on my website. If you're interested I can provide you with the link :)

Cheers

Little column by Liam in MCN about it. Sounds good but that £150 is going on getting my full licence ;)

Im guessing he didn't mention me, as i was the guy that blew the lid off of it all.

Anyway, glad to see you on the site. Hope you put some photos up of your bike. would be good to get a community going for R-125s. Got 30 R-125 riders on there already :)

Hello

I m new here and i come from Slovenia so sorry for my very bad english :) . I have yamaha yzf r 125 too and is great bike. But i have one question. My max speed on this yamaha is 115 km/h or 72 mph. Is this normal? Because the other yzf r 125 owners said that they reached 125 km/h or 78 mph easly and everytime. Is maybe my yamaha restricted? And how i derestricted my yamaha?

Thank you

Micron looks the best but they are no longer available,the leo vincy( 65% weight reduction over the 6.1 k stock system, LeoVince weighs in at a lowly 2.11k !) is good at £360 so is the MIVV GP ti at £320 are now the best full systems imho with the arrow 3rd
