Ninja 250R, 58bhp

[RhynoCZ]

Hello, today I got to this article on my favourite czech motorcycle web, so I thought I'd share with you some of the wisdom that stands behind those 58 ponies.

They used Garrett GT12 Turbo, that gave it 40bhp, then they tuned the DFi, added Yoshimura exhaust system, K&N filter and that resulted in 58bhp. They also say they put on it better tires and brakes.

Still sounds like a heap of crap.

Mighty impressive I must say.

Looks like a neat little install to me!
I wonder why they used a single throttle body and not the OEM twin throttle bodies after the Plennum? Maybe they are using bigger injectors that don't fit the OE throttle bodies?

58bhp for a 250cc twin seems like a decent result for a low boost set up on 100% std engine internals.

But why

I'm sure that in Indonesia they do this kind of thing quite a bit as bikes over 250cc are subject to some horrific import tax or something?

I've also seen a Yamaha WR250X turbocharged to about 50bhp as well on youtube. Also I bet it's easier to ride a 60bhp turbocharged 250cc 4stroke quickly than it is to ride a 60bhp 250cc 2stroke, in terms of effort and commitment required.

The KR1-S made that stock over 20 years ago, probably more fuel efficient too.

I like something that is individual, that said I would happily run my 1990 tzr250 against it

My point is there is no point,

They have made a 250 that is heavier, slower, more expensive and less reliable than a bike made 20 years ago.

It's 200% import tax on vehicles you bring in the country! You need to be a member of the IMI, effectively Indonesia's equivalent of the BMF and have authorisation to entitle you to legitimately import "big" bikes.

No surprise that the Ninja 250 is a big seller because it's the biggest affordable bike that's on sale. I think that the Versys 650 and the ER-6 were recently released there last year. But to be honest, you seldom get anything over 250.

The only place where you can use anything over 10 bhp is on the Jakarta toll roads, which funnily enough, motorcycles are not permitted to use!

Oh, in Indonesia, FAST would be defined as 60mph lol!

turbocharging a 250r ninja wat a load of poop

[stevo as b4]

What would be significantly less funny about turbocharging a ZX10R then?

[lilredmachine]

I consider turbocharging my Bandit to be utterly pointless. I still did it because society.

I wonder if you could tune this to exactly 47bhp? I'd dismissed the Ninja 250 as not powerful enough for my A2 license...

[stevo as b4]

Fools logic!

More revs you say, I personally would like to see that. It's not that easy as just putting in a turbo, is it?

Well it's not the same thing, is it? Pistons and valves, rods and some other bits in the 250 ninja are twice as much bigger than in that CBR. I think the ninja 250 engine could maybe handle 20k rpm, but not for long I say.

That's what's so complicated about adding revs, you've got to make all parts light and strong enough and I doubt that the cheapest kawasaki on the market is made that well.
