You can feel when to shift. Its not about a certain spped or RPM. The optimal shift point is when you stop accelerating. When your body catches up with the bike and it stops pulling on your arms. Rev smoothly through the power band and when power and acceleration fall off(you can feel it happen)fan the clutch and shift up, keeping the rpms up to maintain power. Practice man practice... good luck.

Every bike is different but each bike has a section of the RPM band where it works best. I have an EX250 and the bike feels at its best at around 7k-9k RPM.
Those who drive cars and ride a bike may think that's a high number but considering the redline is at 14k, it's just above mid RPM band.
The goal you're trying to do when shifting is that you don't want the bike/car to work 'too' hard (too high of an RPM) so you shift, but when you shift, you don't want the bike/car's RPM to drop 'too' low to where you're not using the gas efficiently. Also, low RPMs cause engine strain if you're forcing too much gas in.
Once you get to know your bike... you'll be able to tell when the bike is "cheering in joy" and when the bike is "screaming from excessive work". Learning to find that point, is your best bet to finding when to shift not just from 1st to 2nd but from any gear.
Ride on! Ride safe!

it depends on your bike as to which speed you should change gears at...but usually 1st gear is changed very quickly as the gear is only for giving initial momentum to your bike.This gear also has the maximum fuel consumption.Stay in this gear longer if you want to do a wheelie! once started you should try not to switch from 2nd to the 1st gear and stay in the 2nd (unless you have slowed down to almost a complete stop.bikes don't start from the 2nd gear)... i usually change from the 1st to 2nd at around 15-20 kmph on my bike .check your rpm meter for the best change..change at aroung 4000-5000 rpm...

On my EX250 I am shifting between 4,000-6,000 RPM when I am in town, and 5,000-7,000 when I am getting on the interstate. with a top end of 14,000-15,000 (year and weight dependent) I am not using near the power-band I could, but I feel comfortable on the bike, and it doesn't feel like the bike is protesting when I shift at those engine speeds.
for general use though, I agree with quadrailjim. the mid to upper 3rd of the powerband.

--A comfortable time to up shift, is in the middle third of the RPM range of the engine.
--From idle to the end of the 1st third of the RPM range, the engine is just starting to build up momentum.
Shifting in that area, the next gear will put a strain on the engine to get moving again, because of it's lack of momentum.
--Shifting in the top third of the RPM range - the engine is reving free as a bird. Shifting to the next gear puts no strain on the engine. "Things in motion tend to stay in motion."
--Shifting in the middle of the RPM range puts no strain on the engine, trying to pick up speed. As it's spinning fast & free with no resistance in sight. Plus you'll save on gas mileage from not over reving the engine.
