Finally got my YZF R125. Picked it up tuesday the 22nd . Just so happened that after 6-7 weeks of waiting it turned up on my birthday! and there was no rain. Been riding it every day.
I am so looking forward to getting used to riding and taking the corners at a desent speed. (when the tyres has worn in)

Still running it in but i can get 75mph with no trouble at 7000rpm with 3500 still to go and thats on running in oil. so should think 80-85 is there. Not bad for a 4t. Pulled away from my mate in a 1.4 fiesta.

Considering my last car was a 300bhp celica gt4 st205 the YZF feels so quick and i love the fact you actually have to RIDE a bike where as the car pretty much drove itself.

Anyway its saturday morning the sun is shinning so instead of being inside typing on my computer i think ill go for a ride.
Wonder where the road will take me today.

Cheers.
I will get pics up soon as i can stop riding it. If you remember your 1st bikes im sure you understand. Wink
True it does take a while to get there but it aint to bad. I would say 0-62 in about 8-9 sec`s, thats running in oil and not red-lining in any gear. (dont forget 4t 125)
Not bad for a 4t 125.
Any one thinking about getting one, do. Dont listen to people that say they sound like scooters. I havent heard a scooter that sounds like this does. My mate on his RS125 likes the sound more than his (bee in a can).
Wink
Anyway, im off again Laughing

make sure you keep up with your manufacturer services...

i think its an oil change at 250 miles, one at 500, then 1000... after that your on your own.

normal 4 stroke oil doesnt make a bike faster than ''running in oil'', id say your maybe ragging it a bit too much for the running in stage though. you're seriously meant to take it easy.

+1
Give your bike a nice start in life or it`ll be back at the dealers within 3 months and you`ll be hit with a big repair bill.
If you`re pulling away from 1.4 fiestas on a 4T 125 you must really be giving it some mate.
It`s never gonna be a really fast bike anyway so follow the manual and look after the engine till it`s run in..... if you want it to last?

F**king hell if it has a top end like that then forget what I said about it not being a 2 stroke... By the sounds of things this bike is set to redefine the 4T image.
Forget about R6's, VFR's and Speed4's, I want a YZF r125. Well maybe not but I would if it was my first bike... or would I have another NSR? ... meh NSR sorry Razz

EDIT: D*mnit I have to stop swearing I'm suposed to be karma whoring here.

If it is doing 75mph at 7,000rpm and it redlines at 10,500rpm some simple maths would say that your bike is geared for 112 mph.

10500/7000 = 1.5

1.5 x 75mph = 112mph

How fast were you really going?

It might well be geared for 112 mph...but it won't do 112 mph. I once drove an old Austin Maestro 1.3 HLE. Only had 4 gears...3 normal and one badged as "e" on the gearstick...basically on overdrive fourth gear. Anyway, using a formula like the one above we worked out it was geared to do 186 mph! Trouble was it only did 85 in third and 80 in fourth, or "e"!

Mind you, it regularly returned 50mpg.

no, really...
i get about 60mph at 5000rpm in 6th gear
about 70 at 6000rpm
80 at 7000rpm

redline is about 14000

thats just cruising speed though.

flat out in first before it was 33bhp it would hit 60mph in first.

Double checked the speed at the revs and its 75 at maybe 7500 but i aint lying. I have no need to.
Yeah and that really dosent mean the bike is geared for 112mph. Im supprised you think gearing works like that. Gears are set different aint they. 1st is low so pulling away is easy and so is riding in traffic. I would assume 6th gear is set so the engine isnt red lining when going say 60mph.

With the ragging the bloke in the shop said dont `baby` it as it will settle better with normal ridding. On any new bike/car/lawnmower unless you have the patients of a saint you cant be sensible 100% of the time can ya. Ive only rode hard for a few hundred meters out of the 280miles i've done.
I really aint in the need for speed just yet as i only started ridding bikes tuesday gone. I want to learn to keep speed round the twistys. well off i go again.........

Just done a search on google for the specs...
It is said the top speed in restricted form is about 71mph.
Being a 4t i didnt think it would be restricted,but even un-restricted i cant see it getting more than 18bhp at very most.(i could be wrong)
If your telling the truth about doing 75mph @ 7.5k rpm then i cant see it going any quicker,unless your going down a really vertical hill.

So you know,im not calling you a liar here,i just dont believe you Wink

Let's not forget how much speedo's over read.

Doesn't matter how you run them when new as long as it isn't at the same constant revs for too longer time. I've run bikes in at stages and ragging them, never had a noticeable difference.

Get these pics up already. Wink

Well dont belive me then Crying or Very sad all i know is i'm 26 not 17 and have no need to lie about speed to people i dont even know. I could jump into my 3ltr v6 alfa and go fast if i wanted too.
MCM,What bike and lots of others say 80mph is do-able, sorry, an indicated 80mph is possible. I doubt it will go more than 75-80mph in 6th, might even drop a few mph due to the gearing.
I suppose if i did 10,000 rpm ( peak power ish) in 6th and saw what speed i was doing, if i doubled it that would give me a true top speed.
ms51ves3-your good at maths, does that sound about right?
Pictures are taken now comming.........

Yes I know they are geared differently but if you can do 75mph at 7,000rpm in 6th gear, you could do 112mph at 10,500rpm. It's called fact.
My point is that you're either lying, or that Yamaha have designed it like that. If Yamaha designed it like that you will never get anywhere near the redline in 6th gear thus not getting optimum performance and top speed.

Theoretically the bike needs to be down geared so that you are just nudging the redline flat out in 6th gear. This way you will have increased acceleration from the down gearing and a higher top speed from the revs being able to climb to the top.

After your running in process go flat out and tell us what the speedo says. As has been said the speedo could just be over reading a lot so that when you're doing 85mph at 10,500rpm it's saying you're doing 112mph. That would be a serious overread though.

Oh and, Can we have some pictures Laughing

I agree with ms51ves3. He isn't saying that your bike will do 112mph, just that it could well be geared for it. If it is, then with the power it has it won't have a chance in hell of reaching that theoretical maximum (all things being equal, you need around 20bhp for high 80s mph and 30bhp for around 100, so to reach 112 you'd be talking as much as 35-40bhp with that gearing).

Toby: Do you have to read every thread if they're that boring? Wink

Well not being funny Toby R but just dont read this thread. I'm finding it informative and fun. If you have nothing consructive to type then dont type at all. Evil or Very Mad

at ms51ves3, I'll stop talking about speed untill its run in then i'll go for it. Trust me, i aint lying.

Maybe though they geared it to be balls out in 1,2,3,4,5, then economical in 6th? Like i say when run in i'll go for it. I'll see what the speedo says then get someone to follow in a car and get it correctly Right thats sorted now i'll try to get pics up.

Well...kind of. Although wrong is probably, umm, wrong tbh. More misinformed.

Bike magazine - issue 421, May 2008. There's a review on the new YZF-R125. Yamaha say it's 15bhp but changes to the exhaust, fuelling or timing could increase power - unofficially the engineers reckon that 20bhp can be achieved reliably. But, and here's where you're not quite so wrong, that's achieved by tuning it, not de-restricting it as it isn't restricted.

Peak power is 15bhp @ 9000rpm and peak torque is a heady 9 lb/ft @ 8000rpm (both claimed by the manufacturer). Both peak figures arrive 1000rpm sooner than on the CBR due to the YZF having a 58.6mm stroke compared to the CBR's 47.2mm. Yamaha have gone with a long throw design resulting in lower revs and more torque.

Also it is 2bhp more powerful than a CBR-125 which doesn't sound much but works out at almost a 10% advantage and when they (Martin Fitz-Gibbons) tested it he saw almost 80mph on the digital speedo...but with few revs to spare. I reckon that, with some tuning, you might be able to get 85 out of it, possibly a little bit more.

I had a CBR125 when I passed my cbt. It was a cracking little bike...cheap, economical, reliable, easy to ride and, above all, fun. Then I sold it when I'd passed my test and bought a GPZ500S. Now I really wish I hadn't...not that there's anything wrong with the GPZ at all...it's just booooooooooooooring. I don't have half as much fun on the GPZ and, recently, I've seen riding it as something of a chore. I shall be selling it (once it's got 13 mths MOT) and I was thinking of buying a CBR125 as a replacement (I only do 14 miles a day to and from work) but I may well go and have a test ride on the YZF to see what it's like.
