"Doesn't restrict very well"

[HD]

I will be moving from a 50 to either a 600 or a 650 or a 250 enduro. So basically the question is when people say an inline 4 doesnt take the restriction very well does that mean that it can damage the engine or it just doesnt pull very well?

I am fully aware that the sv650 is good because it has lots of low down torque but Im not too mad on the power. An inline4 will be good as it sounds, looks nice. Yes, again it will be more expensive on insuranc, but its a price I am willing to pay. And besides, a 600 restricted to 33bhp im sure will be fine to play with for two years.

Thanks

You sound like you mean GSXR or R6 when you say IL4? (high powered sports bike)
It won't damage the bike but whatever you do, do not ride the bike before it is restricted or you will hate it once restricted.



In before everyone else: don't bother restricting it.

I'd rather have a nice 125 then restricting a bigger engine, or you can get ninja 250rr if you can afford.

Yeah. Something like that. Was looking at the cbr600f as it would be a bit better for commuting. And dont really like the ninjas.

Thanks

The only bikes that don't restrict that well are ones with all there power at the top of the rev range, as the restrictor cuts the top end off big time.

My VFR 800 is restricted to 33BHP and it's fine....

[Frost]

Take a big bike and imagine the power vs rev's graph like this:

https://image.sportrider.com/f/9054496/146_z+2001_gsx_1300r_hayabusa_dyno_chart+.jpg

It's producing more than 33bhp by the time it's at 2200rpm. SO if it were restricted to 33bhp it would have very little of the rev range actually usable. Most sports bikes have a very long 1st gear as they are designed with the track in mind. On the track the slowest speed the bike is likely to do is 50mph+ so 1st gear is designed to be usable at that speed. This means that a large amount of the rev range is used in 1st gear. So only being able to rev up to a tiny fraction of it makes it very difficult to use.

Typically in line 4 cylinder bikes of a given size make more power than say a twin or triple of that size, and will therefore be greatest hit by the restriction. In line 4's also rev higher than a bike of the same size with a different configuration and therefore need to be able to use the full rev range.

[hmmmnz]

get a big single, xr600 dr600 klr etc, they are all about 33hp... at the crank, so no need to restrict, and re sale on them all is far better than most bikes,
you'll be sick of any bike after a few years, so no point buying one that you are looking at keeping untill you are over your restriction,
you'll want a new bike anyway

I'm on a 600 ninja and it took the restriction perfectly well, obviously its nothing like what it should be because theres 70bhp missing. Also like previously mentioned, do NOT ride the bike without the restriction in if you intend to leave it in because you will hate it.

Okay, thanks guys. So basically, dont get a sportsbike And so when people say it wont take it very well they mean that it doesnt perform, not that it will damage the bike in any way?

Also, to add to the list, I was thinking about the cbr, zxr and vfr 400's. Any one got any comments on these? Restricted?

Thankyou

The little sports 400s are fine restricted, they only have 40-50bhp anyway, the major factor is the size. They are tiny!

[Shaane]

[rac3r]

Whatever you get will feel fast restricted...for a while then you will get curious

Okay. Thanks for the comments guys. Quite interested in the vfr 400. One bloke has one literally at the top of my road and I love the sound of it. It also is quite nice looking with West racing decals.

They go for about £1500ish on eBay so that is quite reasonable so what is insurance like for a 17 year old with 1 years ncb (fingers crossed). Also, would you guys advise taking lessons for my test or not? Maybe just a couple?

Thankyou

If your after a vfr400 i'd have a sit on 1 first because there tiny and may cause a problem if your quite tall?

My old zx6r was restricted via the throttle, would be perfectly acceptable coming from a learner legal. Bike still read 125mph and held my own on a couple of trackdays, obviously it was a totally different bike with the restrictor removed.

I would not go down the expensive route of 4 stroke 125's or 250's

Well yeah, im 6 foot ish. Maybe more. Also Im a big build :/

Not too keen on those 3. Would rather go for an sv. How about a cbr600f? Do quite like them and they are more sat up.

Thanks

I don't really know why you'd want to get a restricted machine anyway, personally.
You'd be better off with a 250 designed to make the most of its 30 odd hp without completely capping the engine's output and characteristics.
I can't imagine why you'd want to restrict a 180kg bike down to 33hp when you could have something smaller, sharper and more exhilarating to ride with its throttle pinned open most of the time and responding as it should be.
As said something like the 250 Ninja which used to be known as a GPX250 would be ideal if its a so-called 'sports' machine you're after.
The insurance will undoubtably be cheaper and you'll have a bike you can use to its full potential that hasn't been muzzled.
I couldn't see the attraction in riding around on a 600 sports bike that goes less well than some 125s!

[HD]

Cos then I have a bike to de-restrict that is better. Dont really like the ninja 250. Its more expensive than some others mentioned. I think thats about it really.

Im fine to make the choice of bike from all of the information I have now but will restriction actually harm the bike? Thats the question.
