Appreciation of 250s in the next 2 decades.

[SPman]

Inline four 250s were made to fit legislation in Japan and not for any other particular reason. 2 stroke 250s are meant to be little GP250 replicas but are generally owed by young hoons who rev the snot out of them and blow them up coz they skimped on the ring replacements and top end rebuilds.

Consider that the 4 cyl 250's have similar outputs to the race 250/4's of the 60's.....

Depends how you measure value.
The Ducati 900 I bought in 1986 for $ 2700 Aus, is now worth about 7K NZ...
From a $$$ point of view the Z1000 I sold would have been a better financial investment.
However riding the Ducati with friends, listening to bellowing exhaust and whiring bevel gears is priceless.
There will probably be no petrol in 20 years to run them on anyway...or have I been greenwashed.

Well looks like I've been totally pwned here. Dam.

[Harvd]

Looking at the new acc levies i would say yes!

[manxy]

I love strokers, I've had a couple of 250's and a rz500, wish I'd kept that! Be worth a packet now.
I bought a 93 RGV a couple of years ago for 2.8k and have been offered up to 4.5k for it.
I keep it in good nick and don't put many k's on it because I know it's going up in value, alot more then the fours.
It's a bike for an hour on twisty roads, more fun through them and faster then a bigger bike.

Holy thread dig batman

I'm going to say the 2-strokes will have it.
My explanation is "dragons teeth".

[Sable]

2 strokes. Nothing else like them, simple as that. Even if they do bring in DI 2 strokes, they will be a completely different beast.

[Asher]

Depends on what bikes you look at, the rs250's, rgv250 vj23, later models nsr250's will defiantly go up in value while some of the other (older) 2 strokes probably wont.
But i can imagine a few of the 4 strokes to go up in value too like the mc22 cbr250rr and pre 94 zxr's

Old RD250's haven't gone down in price since the 1987 Market crash.
TZ's are worth more than a new 250!
Don't even get me started about Bultaco's

[actungbaby]

yeah yeah

But that was 2009 orbital dont seem produced anything for the market in all years been going on
Apprently they had a deal with gm for cars

damm only 4 storke i need least 50 to get going hehe

Well as the fuel is injected directly into the cylinder, the oil is separated from the fuel and is used as a dedicated lubing system. This means none of the blue smoke puffing out the back, and not so much of the blowing up because the parts are getting properly lubed instead of the not very good fuel/oil mixture.
Fuel doesn't get thrown straight out the exhaust port either, which means a more emissions friendly bike.
From what I know they are also tuned to be less peaky and have powerbands more reminiscent of four strokes than classic two strokes.

There was a really good article on here a while ago about an Aprilia RS250 that had been fitted with a DI system. The sound was something between a four stroke and a two stroke.

Edit: Here's the article (I think): http://twostrokemotocross.com/2009/0...s-strike-back/

Seriously how expensive is it to re build a ns 250 r crankshaft do they use plain bearings or rollers

Are they replacment aftermarket parts still availble for these machines ?


I think come down to machines that have more about them from the competion

I chosse a cb 250 rs vt 250 cbr 250 because of hondas gp exp with these motors back in the 60s

In 250 2 strokes maybe the kr 250 good and more rare rgv 250 suzuki or yam model as yamaha had great

Line of these Little beasts of many many years, but really if you love your bike from the past go for restore it

You really have no idea what you're on about, do you?

I realised this when my dad took my '92 Bandit 250 for a ride. And that's not even a hot CBR250RR, ZXR250 etc.

Keep in mind that he hasn't climbed on a bike since the mid 1970s, all the bikes he rode were old 300-500cc Brit thumpers, usually in varying states of disrepair. Since then he has had basically no contact with the motorcycling world.

Firstly he couldn't believe that liquid cooled 250cc inline fours were being mass produced. The smoothness of the engine and redline absolutely blew his mind (that's only 17,500rpm, don't the CBR250RRs hit the limiter at 19 grand?) and when he got back from a short ride he assured me that my bog-standard old Jap 250 would have been considered a crazy quick machine back in the day.
