sv650 restricted performance

[stranger12]

hi all,

does anyone here have a restricted sv650 injected model to advise :

what is the top speed,

is the acceleration(0-60) impacted, i know it is 3.6 unrestricted . that figure maybe based on someone whom is 60-70kg but i am 128kg so guess that may be different . what do you think the 0-60 will be with me on it and also with someone whom is 60-70kg not considering riding techniques, weather etc .

would the mpg improve ?

many thanks

110 indicated from mine. 0 - 60, good enough

what do you consider as good enough

[Supermoto_Fan]

Never timed it, under 5? What's the big deal! Any bike you restrict to 33bhp is only going to do a ton at the most so pick one on other factors over speed

I've only seen 105 indicated on mine, but I'm not tiny. Might go faster downhill - that was on a reasonably level surface and not on public roads, officer

I haven't measured a 0-60 time. It won't be as quick as an unrestricted bike. It's quicker than (most) cars away from traffic lights. Unhappy pootling along behind a car at 60? You can get up to 80 and back to overtake in a relatively short space of road. good enough? yes.

As for economy, I was getting 55mpg when I first got it. That's dropped to 50 mpg as my confidence has grown. Not sure what the figures for an unrestricted bike are.

thanks, how does it feel when restricted , does it stop reving from a range (7-8k above), is it sluggish ?

or guess the restriction only come into force when you are doing above 80-90 miles which the bike does not rev etc

[G]

You're looking at around 6 seconds or a smidge more to 60. Possibly then a little bit more due to weight.

[G]

It feels like a bit too high geared bike with 33hp.

So, compared to a full power SV used properly, yes, a tad sluggish.
Compared to another 33hp geared the same - well, feels similar .

The bike is clean to redline in all gears except top, where it will not budge over 7.5k revs no matter what you do.

Very strange
My '11 er6n (@33bhp) Pulls up to 100+ no problems (tested on a private strait )

It also got up to speed, and was pulling away from a thundercat and ninja 600 which where also restricted to 33. I have also had my brother on the back, cruised happily at around 6k in 4th @ 90 (again on said private road)

As soon as my house mate passes his Theory+DAS (teaches the bastard buy the bike i wanted) he's picking up a k9 sv650s so I can test it against that,

I have a ECU restriction, so anything over 6/7k is basically noise with very little pull - I wonder if the restriction or engine/gearing design makes all the difference?

For a certain power (33 bhp) and torque curve, which are generally similar for a given style of bike, the maximum speed and acceleration will be similar even across different manufacturers.

You're looking at about 6 seconds to 62, around 110 top speed. If these performance figures bother you that much - and you want specifics - why are you even bothering to restrict it?

< 6 seconds is 'sports car' territory...

33 bhp is 33 bhp. It is the amount of power a 2 stroke 125 makes - you need to have realistic expectations!

well the 0 to 60 does bother me as i am seeing a 3 sec increase which is huge. the best way would be to try it i guess.


i thought based on these posts the bike is restricted in top gear thus 0 to 60 should not be impacted

by the way my current bike is 125 4 stroke (11 to 13bhp) and does 0 to 60 in an hour or so so really the restricted bike is not the same but way quikcer than 125

I have a 11 model er6f and the restrictor is ecu and a throttle stop, has yours not got the stop ? as the ecu just changes the fuel map i believe- bloke in shop said it would just use more fuel for no gain if i put the ecu to normal and leave the throttle stop..

[stranger12]

what does the throttle stop do ? stop you from reving form a range upward and how much the restrictor kit did cost you ?

[Supermoto_Fan]

I had a full 15bhp 125 and even then 33bhp feels like a rocket for a while. Stop being so pedantic.

The OP is curious about the power of 650 restricted, I know I was when I got mine. A 22bhp is a big jump and feels more than it sounds. The benifits of having a 650 @33 to a smaller bike built to 33 (other than the obvious) is that you still have the a bigger torque, traction, styrdyness and weight increase. This really inspires confidence and roa dominance. 33bhp Is more than enough to have Lots of fun, you can cruise at far more than motorway speeds, and get there very fast (compared to most cars)

The throttle stop is a screw on the throttle body that stops the throttle fr being completely opened. Some bikes have it as a peace of metal on the accelerator. It literally stops the accelerator from opening to a certain point.
I'm unsure wether my er6 has one installed as it full revs, but It came from a Kawasaki dealer with the certificate and I know there is definitely the short cable in the ECU diagnostic port, and I have no intention to remove it until I'm legal.
33bhp and the torque of that bike is more than enough for me, as it is TINY.
Iv jumped up from a 11bhp ybr.

Btw, easiest way to restrict an injected sv is by swapping the ecu for a restricted one. Piece of piss.
Alternate method is washers to restrict airflow into the engine and a throttle stop to restrict how far the throttle can open.

you talk about 0-60 speed and improving mpg at the same time, madness

Bike had a full service yesterday.

109 indicated today same private road as before, officer

Had to duck down a bit to get out of the wind, but otherwise it felt stable enough.

As the first response put so concisely, it's good enough.

But seriously, if you passed your test before 13th Jan why are you still on a 125? and if you didn't, why the interest in 33hp restrictions?

[stranger12]

the 0-60 and mpg are against each other but just wanted to know

i am not going to be doing 0-60 at every traffic light

the reason i ask is i love to experince the daily 3-4 sec that is a dream when you are comming from car background

my car does it in around 6(328 modified e36). i know bike is a different beast all together but you can still get the excitment and happinies that isn't cheap on cars

thats all


by the way, if i simply put the cpu in, how can i trust that i am legall. fair enough the seller does say it is 33bhp but what happenes when i am pulled over by the police?

thanks

[G]

Maybe you're different.

For me, I found I very quickly got bored of the acceleration from a bike.

That doesn't mean every set of lights isn't a test of acceleration.

And for that, as I started on bikes, never found car acceleration massively entertaining either. (I have an E36 M3 and a kit car, but of course neither will come close to a litre bike off the line or at speed.)
