Was just wondering as im looking at something with a little more capacity till i can be bothered to do full test, about a aircooled 125 4stroke.

Likely to overheat being aircooled?
or have things moved on since overheating bikes?
cheers

They'll still overheat if you're stuck in traffic for a while. Fine for normal riding though.

Because it's tricky to give a hard and fast rule. Laughing

Depends on the ambient temp and the speed your were travelling before you stopped etc. etc.

If could overheat it by filtering through a town centre for 10 minutes in the middle of summer.

Just buy it, stop worrying. 99% of the time it will be fine. I'm only really taking if you're filtering for ages in town centres or if you're stationary for ages with the engine running on a hot still day.

I need summin with some fairings, going to be parked in a college carpark, unfortunatly the likelyhood of mudskippers being hotwired is much higher no? all the ignition wires etc are flapping about lol

If someone really wants it they are going to nick it.

Just get a big fuck off chain to lock it to something to put off the opportunists.

I have a chain but as almax showed even the sold solid ones are like cheese with bolt cutters.
So unless i buy a almax itll still get stolen by a prepared theif. just not sure how likely it is to get stolen aka a new college lol. had loads of mates at old college who knew my bike and would of likely seen it going. but know no one at this new college.
hmm

as far as overheating goes...

iv got a Honda XLR 125 which use's the CG/CB 125 engine i think? but anyway that is air cooled and i have put that thing through some tough travels

in the summer i did a full 104 miles without stopping the engine both flat out on A roads & in traffic it didnt do it any harm what so ever those little honda engines are tough little things!!

every weekend i do 2 38 mile trips which is mainly flat out all the way its not ever given me a problem and its been doing it since jan of this year

A 125 will not exactly melt its casings will it.
My divvy is aircooled and gets bloody hot. I got lost in Bristol centre at rush hour for an hour, and no probs.

Didnt say melt its casings, im more worried about piston holeage.
and general overheating, remember when i used to have aircooled minimotos, 30 min stint and it be dead for the next 15 Razz lol.

its fair to say that a mini moto wont get as good cooling as a proper bike just like my old piaggio NRG wouldn't be cooled as well as my XLR as the entire engine is open to the air whereas the little NRG has a meer fan on the flywheel to cool it

mini moto's are just cheap fun, proper bikes (specially the geared honda 125's) last and last loooong

Stop fretting, it'll be absolutely fine.

Honestly if you can run a CG around Dubai for a day Britain will be no problem.

CG's rock! Very Happy

is it just me or are Honda engines literally bullet proof?!

iv had 3 honda visions and my XLR and iv never killed or remotely damaged one...

whereas my pug speedfight, endless piaggio scooters, kawasaki kmx, yamaha TDR (list goes on) have all had some sort of engine problem???

gotta love honda!

Silly question why does it have to be aircooled?

I really doubt someone would put loads of effort into stealing a £175 bike. If they were going to steal anyone's bike it would be the nice new shiny one next to yours.

Why does it need fairings?

4 strokes need maintenance too - they'll take longer to blow up if you don't, but will cost more when they do.
The RS etc is generally rings done at 10k miles; simpler than doing shimmed valves on a 4 stroke (though simple 4 strokes are generally tappets).
Shouldn't be a problem with over-heating when idling; don't make enough heat in the first place.

my YBR can do 20mins at 60mph easily and sit in stop start traffic for 30mins and not overheat.

Just if your going to stop start keep the revs low and dont rev it while idling. These bikes are designed to work in far hotter temps than what were riding in.

Same here, no problems in busy traffic or long (30 mile +) NSL runs. If I'm at a standstill and I know I won't be going anywhere for a while, I switch the engine off anyway. These engines are tough. Thumbs Up

They aren't going to overheat unless you do something stuipd like ride around in second gear on the redline all the time or sit revving the nuts off it while stationary.

It's liquid cooled bikes that tend to overheat in town.

It doesn't matter what sort of chain you use, if they want it, they will have it.

The sort of person who is going to steal a 125 is a wee ned out for a joyride. As such, if the wiring was behind a fairing, they'd just snap it off to get at it.

Most of them would cut through your chain/whatever it's chained too then push the bike somewhere secluded to hotwire it. As such, they can afford to take their time.

A fairing on an air cooled bike is a liability, reduces air flow over the engine.

I wanted fairings as im a bit of a tart Embarassed haha
I thought 4 stroke maintenance was alot more secluded like oil change and filter and valve clearences/shims or whatever its called at a high mileage.

Id get a RS but id end up poping a piston within a week or so, and i havnt yet got stuck into mechanical work on the bikes properly, so dont want to try it and then be without transport when i possibly cock it up.

Basically i want a 125 as i cant be asked to do big test yet,
but my budget is only about 1300, i dont want to do regular maintenace like 2strokes really so was looking at summin like a cbr but the price of them is higher than i expected...
