Not knowing what bikes you have imported into OZ, I can only go off what bikes I know.

There are the Kawasaki Balius 250, Kawasaki GPX250R, Honda CB250 or it may be the Nighthawk 250 over there, Honda CBR250RR etc.

All are 4 strokes, all very proven and reliable too

I would rather have the fast scream of a 2 stroke than the slow drone of a 4 stroke. Like comparing the scream of an F16 to the drone of an airship Wink .

The CBR should be a fair bit quicker than the GPX or ZZR250, although both of those 2 are very good on fuel (less of an issue in Aus where petrol is far cheaper than the UK).

Basically to get any reasonable amount of power from a 4 stroke you need to rev the nuts off it (hence why the CBR250 red lines at around 19000rpm, against ~12000 tops for most 2 strokes). To rev an engine you need a short stroke (basically the average speed of the piston is pretty much a fixed maximun), so to keep the capacity you need a larger bore. However a larger bore results in a worse combustion chamber shape and a poorer burn. Solution to this is to use a short stroke and a small bore, but just add a few cylinders instead to keep the capacity.

All the best

Which honda took to an extreme in the 1970s and made a 250cc 4-stroke race bike called the S6 which had six cylinders, desmotronic valve gear and about 14 gears. Redlined at 18,500rpm..air cooled. You can buy a replica if you have a couple of hundred grand to spare and a team of japanese mechanics to rebuild the engine every 500 miles Very Happy

2-strokes rule. If you are still allowed to buy strokers over there, get yourself an RGV250 before they are banned. You will not regret it. You will not be able to hear the engine anyway on account of the manic laughter/screaming inside your helmet.

Its the RC165 250-6

air cooled 247cc DOHC transverse 6

7 gears
153mph top speed
front & rear drum brakes
6 cylinders, 6 carbs, 24 vavles all in a 250 4 stroke, all in 1964!

So far as i know none still servive outside of musiums. an american company did make a few replicas which are still ocassionally run, but chances of seeing one are very slim! Sad

I'm a big fan of the Suzuki RS67

liquid cooled V4 2 stroke 125!!! Shocked Laughing

Most states in Australia introduced power-to-weight ratio limits to stop learners riding RGV's after high accident rates.

There's a Hornet 250 (similar mechanically to CBR 250) and there's a VTR 250 out there too.

Powerfull engines generally have a higher pitch.
Listen to a F1 engine and compare it to a harley.
The harley may sound meatier, but probably has 20x less power or something.

Even the CBR250 etc have a fairly high exhust note, so it's your choice... Have a fast bike, or have a slow bike that sounds nice (you can always rev it on your lawn Razz )

I never used to like the sound of 2 strokes, they allways used to sound like mopeds to me.
250 2 strokes are more of a 250GP scream and a moped whine.

Nothing beats a stroke screaming in the powerband up through the gears! Very Happy

Because two stroke engines produce power on every piston stroke, rather than on every other piston stroke as with four stroke engines. For more information, look on https://www.howstuffworks.com

As far as I am aware, the type of engine fitted has no relation to the type of starter fitted.

Well in a way it does.

2 stroke 250's are typically made to be road going versions of a race bike. These are normally performance bikes which are designed to be as light as possible and go as fast as possible.
Kick starts weigh alot less, hence most performance 2 strokes are fitted with a kick starter.

Non-performance bikes are normally electric start, or electric and kick.

Go for the cbr250rr, if you are on a tighter budget get the cbr250r

Both are good bikes, the RR is a touch better with twin discs and few other sexy addons.

Have a look in my profile for an over-view and photos.

i dont know many production bikes that dont come as standard with and electric start. i think even honda cg125's have em.

bandit 250 all the way. 250 IL4 16v. they are really quick, about 100mph 33bhp restricted but i guess around 110-115 at full power?

Suzuki RGV250 2-stroke: 135mph, 60bhp

Honda CBR250RR 4-stroke: 120mph, 40hp

Twice as many bangs per engine revolution. They rev higher too so they wear out quicker. They also get the arse thrashed off them all the time.

IMO the smell of burning synthetic 2-stroke is the smell of speed. Castrol R (which they use in classic racers) is the best ever, I know people who put a few drops in their petrol tank just to get the smell. I could stand and smell the exhaust of a racing 2-stroke all day Smile

As has been said, kick starts are lighter. It is also no effort to kick over a 2-stroke and they rarely kick-back like 4-strokes can. A lot of people were put off bikes in the past because they find it too much of an effort to kick start them or have been injured by a big 4-stroke (an old Panther 650 WILL break your ankle if you do it wrong), the manufacturers are just reacting to this. There is no real need for a leccy start on a 2-stroke.
