midrange

Has anyone tuned a 10R for midrange power? For street use the motor doesn't appeal to me. I'd buy a new RR tomorrow if I thought I could get anything out of it. Maybe with cams or cam timing?

Full exhaust and a sprocket with a tune is all you can really do. It's built with top end in mind and you'll compromise too much to get just a few extra with cams. You won't need anything else after its flashed, tuned, exhaust and sprocket anyway

Its difficult to take you seriously sokmetimes...

The guy is asking how to increase the mid range because he's rode the bike and for him it needs more power and youre giving your standard reply of keep it stock. He asked what he needs to do to increase the mid range.. You have no idea what sort of rider he is and how much seat time he has and seat time doesn't increase power, it just makes him more used to a restricted down on power bike.

earlier Gens you can swap down cams.....Gen 1-3 swap easily. Untill we get variable cam timing, it's one world or the other.

Unless you open the motor, deck the head and run a thin headgasket, then you can have a good compromise of mid and top power with the right cam timing.

You're not going to get very good midrange out of most literbikes.

The ones that do?
Ducati 1299s (not even the 1199 since it has poor midrange)
Aprilia RSV4?
2017 Suzuki GSXR1000 (with variable valve timing)
Yamaha R1 cross plane

Others? I can't think of any.

Ive ridden crossplane and s1000rr and i can safely say s1000 has nothing on crossplane.
Crossplane grunt is epic.
S1000rr is docile in comparison but has the extra bhp to whip the crossplane higher in the rev range.
If you hit a bump in the road whilst on a crossplane then youd better be holding on tight as it can snatch the bars out of your hand.
The snatchyness is its downfall unfortunately

The zx10r isnt renowend for midrange.
The problem i think is that the whole engine is designed for top end power. People say you can tune the bike to get higher torque but you will also get higher bhp in that same area so its just making the bike more lairy. What you want for the road is more torque and less bhp in that same area so you can ride on the engines grunt.
After riding a big bang r1 that was tuned i can say forget about the torque if you want to stay with the zx10r.
The big bang smashed my zx10r on grunt by a massive amount.
If the big bang wasnt ugly and snatchy on and off the throttle id say it was the best superbike for the road.

I have and have 185 rwhp on mine. Spend $10,000 on various mods and here's my result. I replaced the mid pipe with the converter. PLUS AKRA SHORTY WITH THE PLUG REMOVED (!!!!) with a ecu reflash, bazzaz and custom map, my bike is smooth and fast from bottom to top. I am up 2 in the back and there isn't much that can pass me. I have the secondaries removed too.

GenII, end of thread. After extensive mods to my G2 the power comes on strong around 6K and is a freight train til about 12K.

Again and again I repeat: no reason to do anything to this bike or any liter unless you're totally dialed into the bike on both street and track and then you may have to adjust cassette for a particular track to pressure the mega fast guys.

Simply asking the question about mid range begs the question about skill level. Get Code's Twist Wrist II and take his superbike classes using his rr's.

If you google zx10r dyno charts there is a brilliant picture of 2012 zx10r versus all other superbikes available at that time.
It shows what im on about.
You can increase the torque but the shape of the power curve is always leaning towards top end power.
What i found interesting is the rc8 must be absolutely awsome on the road. Massive grunt and a very torquey power curve.
Infact id bloody love to get one.
The honda has good power curve for the road.
The zx10r is quite flat and good for track riding.
And the s1000rr is a beast.

It is a racebike, that's where it wants to be, above 10K. Not as easy or fun to ride on the street as the 2017 Z900 which has massive low-end/midrange but hits rev limiter at 11K, just where the Gen 4 wakes up. I have both.

A reflash will remove timing retard for the first few gears but the TC will still limit your power if ON.

The ZX-10R is not cammed or tuned for serious low-end.

Thanks to the CHP getting more $ I need to build a track bike, so midrange is no longer the issue. I was wondering if the '19 got anything so special it would make it worth the current $2k price premium and the hassle of taking out the ABS, or if the '18 is the better deal.

Fast lap times are made by being fast everywhere.
My local track has 4 hairpin corners and although my laptimes were good i recon i could be 2 seconds a lap faster if the zx10r had more grunt. I lost on every tight corner to most other 1000 makes.
They would always stretch me.
On faster flowing circuits you can keep it in the rev range easier so its not so much of a problem.
But for tighter tracks its hard to ride quick.
Thats not just me thats most testers that say that.
I just get slated because people think im a kawasaki hater. Im really not. I love them but to compete in the future they need to address this issue and i fear they are falling behind which is sad.

ECU flash, Kit cams and head gasket improved the mid range on my 17 RR. A full system with a long mid-pipe helps too.
Still no grunt of a R1 or BMW, but it makes over 200 hp.

Re-gearing makes it "feel" like its got more grunt. -1/+2 was too much for me with the added power. But around town it would probly work for you.
The ZX10 is not a great bike for the street. The 04/05 had all the grunt.

For the street I much prefer my BMW.

I'm gonna be trying -1/+3 this weekend with all the mentioned mods (except kit cams, just retimed stock cams). :badteeth: How was the wheelie? hahaha

Maybe it’s the video that makes them look close, but those trees on that track seem like they are in striking distance.

There's plenty of space. And a chain link fence...I'm more worried about that actually.
 
#33 ·
I did play with the gearing quite a bit and its better but created a tendancy to wheelie more.
Today i test rode the new aprilia rsv4 1100 factory and im convinced kawasaki need to change something to keep up with bikes like this.
But if anyone cares what i think I still prefer my r1 to the aprilia coz its got so much grunt its insane. Plus the aprilia is too expensive
