Micron MotoGP Exhaust

[sunama]

Hi,

I'm looking to buy a Honda CBR125, 2006 model. I've put down a deposit on it, however, I am having a rethink. Below is a picture of it:

As can be seen, it has a Micron MotoGP exhaust.
The MOT is due in May 2009. Will the Micron MotoGP exhaust pass the MOT?

If not, can I simply buy a stock Honda exhaust and replace the Micron or is it more complicated?

Thanks

Ok.
Thankyou gents.

How much you getting it for?

£1200. (+ CBT cost, insurance, security equipment, MOT, road tax, helmet and clothing).

The exhaust doesnt bother me. I just want this bike for commuting. I'm not trying to look cool or anything.

I would much rather get a bog standard scooter, but I dont want to forget how to use gears, should I decide to go for my full bike test in a few months. Hence, a manual bike is the only way to go for me.

I've been tempted to get a cbt and a 125 for ages now. Just the cost seems a lot but i don't particularly want a 'slow' 125.

I dont understand the obsession people have with speed. This bike will get to 70mph without too much problem. Any faster and you will be breaking the national speed limit.

The only reason why I would want a more powerful bike is if I decide to carry luggage or a pillion passenger (ie. to deal with the extra weight).

I dont see the point in breaking speed limits, getting points on my license and paying unnecessary fines.

Perhaps there are other reasons for the extra power (apart from showing off), but I cant think of any.

You may feel different when you actually end up riding a 125 regularly. It's not just about top speed, acceleration comes into it too, and being able to get up to the NSL in a few seconds is awesome fun . I suppose it all comes down to whether or not you're a biker, or just someone who wants to commute.

Initially, I intend to use it for commuting. However, this doesnt mean that I dont enjoy going fast.

What I don't understand is people racing to the next set of traffic lights, which are placed very close together, in London.

I would love to try bike racing, as I enjoy go-kart racing and racing simulations, but to do this sort of thing on London roads is pure madness and will almost certainly end in an accident, getting points on my license or a big fine. I don't see any upside.

I totally understand the concept of taking your bike to race track and pushing the bike to its limits - the thrill of faster lap times is addictive.

Speaking of 125R's, anyone know if they come with immobilisers as standard?

honda cbr125r = no immobiliser.

You can buy and fit a £25 cyclone alarm which includes immobiliser.

Surely though, if you want 25bhp, why not go for a larger, more powerful bike? You will save some money in the process and remove the hassle of having to make the modifications.

People forget that 125cc bikes carry a high demand and for what they are, they are pretty expensive. Especially when you think that I couldve got a CB500 for less than I am paying for the CBR125. The only problem is that I dont yet have a full license so have no choice.

I would certainly prefer a CB500, over any 125cc bike, mainly due to its extra horsepower, allowing me to carry items/luggage without any problem.

hmm, another thing is, inevitably your gonna get chavs trying to race you thinking its a missile which is just going to lead to major embarrassment!

But, why would you race them anyway? If they want to act like schoolboys on the road, it doesnt mean you have to?

Plus I always had fun racing other 125's on an underpowered bike. It fairly shuts up the aprilia fan boys when they get beat by 50's or 4t 125's

Aaaah. So you are skillfull rider. You are effectively handicapping yourself when taking on the faster bikes.

I've only just started motorcycling and I hope to be able to have the skill to pull of traffic lights and be able to beat those on more powerful bikes. Of course, I won't use that skill on traffic lights as I feel its a little silly.

Anyway gents, I've just returned from buying the bike. I rode it from East London to North West London.

The verdict:
Regarding the exhaust: its VERY quiet, which is probably as result of having the baffle in tact.

Performance:
0-40mph: The bike accelerates fairly quickly to 40mph.
40-50mph: Acceleration to 50mph is a bit laboured.
50-60mph: Once you hit 50 mph acceleration is very laboured, though I was using 6th gear. Apparently on the cbr125, its recommended to use 5th gear and use 6th only when you are going downhill and are hugging the fuel tank (aerodynamics).

I'm still learning how to ride a bike, as I have only just passed my CBT and I'm learning that the CBR125 has a very clunky 1st to 2nd gear change. After that, its smooth.

One thing of note, regarding speed limits: I was on the dual carriageway for a long time and I was observing speed limits strictly, however, I was finding A LOT of people zipping by me in cars. If my speedometer is anywhere near accurate, I know for a fact that many cars were breaking the speedlimit.

I can certainly see why people would want something more powerful, but I can see people breaking speed limits, fairly easy with faster bikes, without even realising and as a result getting license points and fines.

EDIT: I also wanted to add that after squeezing the throttle tight, continuously my forearm is aching. Is there a technique that I'm missing here?

Looking at getting on of these for my first bike, with a few others in the frame, might buy it new but I dunno yet.

Don't buy it new. It just isnt worth it.

This is my first bike and I've only ridden it for a little while and I can already see that it is a bike used purely to gain practise/experience/confidence on, whereafter you take your full bike test and buy a more beefier bike.

...and this coming from someone who doesn't believe in breaking speed limits.

The only thing that makes me feel good about this purchase is that I feel I got a good deal and that it serves its purpose. I would be gutted if I had paid £2500 (or whatever it is new), knowing that in 6-12 months I would take my full test and sell this for around £1000 less.

When you are more comfortable with the bike you could start to do clutch-less shifts which, if done correctly, provide a much smoother and quicker gear change than one using the clutch.

I actually heard that clutchless shifts could damage the gear box/shift mechanism, otherwise, for me, a semi-automatic gear box (ie. clutchless shift), is certainly the way forward.

Some Ferrari cars have the semi automatic gearboxes where they have paddles behind the steering wheels - something copied from F1. For me semi automatic gearboxes on cars and motorbikes are the way forward.

Do you have any tips on clutchless gear shifts?

This is indeed a VERY old thread of mine.

What I was looking for was a reliable 4 stroke 125cc bike. I believe the CBR125 is the fastest of these. All the other 4 strokers are either VERY expensive or are slower.

CBR125. The bike whose picture I posted in the opening post of this thread.

The micron GP exhaust was not a problem during the MOT, which the bike passed with no problems.

I do find that it is a small bike. Its a beginners bike, to give the rider road experience.

Personally though, having seen the really large bikes the smaller ones, I prefer the smaller ones. The closer my head is to the ground, the better.
