Hey, guys

My bike seems like the gearing is really low! On the freeway, I'm hitting very bad efficiency since my bike is around 7-9k rpm constantly in 6th gear. I'm having trouble keeping up with a Honda Rebel! Seriously...I can barely hear the Rebel's engine while my CBR is screaming just to cruise along side it :O Does anyone know the stock front sprocket gearing? I'm positive, it's swapped!

 

Stock is 15 front and 43 rear.

 

Thanks! I was thinking about buying a 13 tooth front while keeping the 43 rear. Would that be possible without swapping out the rear sprocket? I'd probably would just have to adjust the amount of chain links.

 

Yeah that's possible but it'll make the rev's even higher with a smaller front sprocket with only thirteen (opposite effect than what you are after)

How many teeth on your rear sprocket right now ?

I would start by reducing your rear sprocket first if you are looking to lower rpm's

 

I'm running a stock sprocket in the rear. Which one would be more cost effective? Raising the front teeth or reducing the rear sprocket? I use the bike for cruising on the freeway 90% of the time so I'm looking for maximum cruising efficiency. I rarely go to the mountains. Looking for the highest possible gear ratio I can set up.

 

lulz 13 in the front would be like + 9 in the rear. Think of it like a mountain bike... If your front cog is smaller and your rear cog is bigger, then you top out really quickly and your mt bike is really torquey. However, if you slam the bike in the biggest front cog and the smallest rear, you have absolutely no torque but you can just cruise with little energy

Play with that site and see what you want your rpm's to be at for a certain speed and adjust your sprockets that way.
I would recommned changing both sprockets and chain as one.

 

Thanks! The site helped a lot. Never knew such sites existed
