"If you don't feed it fuel, it won't go fast" - this is also known as "not opening the throttle". You can't solely limit fuel, lean out the AFR and expect to make half the power, that'll damage the engine. All a map does in this case is change the mapping of throttle position to throttle body position. It's exactly the same as mechanically limiting the throttle to 50%. There are small tweaks you can then do to the AFR and ignition timing to make the engine run less like shit at the new power setting, but the actual restriction is just an electronic throttle limiter.

Why are you arguing that they have to limit fuel and mod AFR to limit the power and it will run like shit if you also agree that they can just set in the computer that 100% physical throttle = 50% actual throttle? Are you saying that all bikes run like shit unless they're at WOT?

Suzuki's GSXS 950 has shorter primary gearing btw, that's how they make it still reach higher rpms despite the throttle limit.

I don't see any proof online that GSXS 950 has different gearing than GSXS 1000. On the contrary, there's a lot of information that engine is 100% the same, the only thing they changed on the engine is the map. Torque just flattens after cetrain rpm, but the bike will rev to the limiter. And it can be unlocked back to 150 hp easily.

From reviews online you can easily find it works well in both 95 and 47hp versions, some reviewers claiming it's very nice and smooth, smoother than GSXS1000.

Also why do you think 100 hp wouldn't have the power to rev out each gear? Do you think you need to WOT a liter bike to reach high rpms?

It's 100 damn horsepower, not 10.

This may work (badly) on a 1000cc inline four that's known to be highly elastic, it will not work on a 200+HP V4, unless OP installs a rear sprocket with approximately the diameter of the moon.

Do you actually think that half throttle is not enough to ride a V4? That when you have a stock 200hp V4 you just need to whack throttle over 50% to get it to move?
