Hey all,

Just joined this awesome forum a moment ago to ask this question.

I bought a 2013 CBR500R about a month ago. My first street bike but I have plenty of experience on dirt bikes. Really happy with the economical aspect of this bike, as well as the stylish looks, also appreciate how chill and easy it is to ride.

Anyway, I went nearly 100mph on the highway earlier today and I noticed it was absolutely screaming in 6th gear. Like nearly 8000 rpm. I didn’t really like that considering it redlines at only 8500. I felt like I was abusing the bike.

Any thoughts on this? Is this normal? Should I look into different gear sprockets?

I hate to say it but I am already kind of wishing it was a tad faster.

The stock gearing is great for city riding but you can always go up a tooth on the front sprocket if you want to bring the revs down a bit on the highway. As far as reliability goes, a few minutes at 8k here and there should be fine but I wouldn't want to keep it there for hours at a time.

It's been geared for purpose (City), and doesn't really have enough torque to push it through the air at obscene rates of speed.
Stated top speed from Honda is 185km/h (115mph), so you weren't far off from maxing it out anyway. If you plan on doing a fair bit of 'over the limit' speeds, the 500 is not the bike for you.
For reference as far as swapping sprockets go, check out www.gearingcommander.com to see things change with different ratios.

Honda gears its CB-500 models waaaay too low. Great for wheelies, should anyone be so (immaturely) inclined, and good for quarter mile times, but not good for cruising at more than 60 mph, IMO. I noticed this low gearing before I'd gone a full mile on my new (in 2019) '17 F model. I kept looking for another gear!! The largest counter-shaft sprocket available or that will fit, is a 17T. Mine from Sprocket Specialists cost $33 shipped.. The crankcase saver, (in front of the sprocket, protects the crankcase in case of a broken drive chain) needs to be removed, temporarily, and a wider radius ground into the case saver where it faces the counter-shaft sprocket, else the sprocket won't fit. It's not a difficult job and there is a descriptive thread on this forum. Search function will lead you to it. It is not a difficult job. You'll be glad you undertook to do it.

After 4000 miles, I am very happy I got the 17T sprocket. It drops engine revs by 600 rpm at 60 mph (indicated). Note that this sprocket swap raises gearing by just over 13% and your speedometer will read a bit low as your speedometer counts counter-shaft revolutions, not rear wheel revolutions.. Given that the speedometer is optimistic anyway. I just add 5 mph to the speed shown and have no worries about being cited for speeding. When computing your fuel mileage, remember to add 13% to the trip mileage shown. My CB-500F consistently records mileage from 70-77mpg, depending on how I ride (usually very moderately).

Ralph.

A few years back I went the other way with 3 down in the back, and dropped me 400rpm at the save speed. I guess to save from grinding the metal part you could've done a mash up between the two and gone 1 up (f) / 2 down (r).

I know stock my bike was about 7% out with the speedo. That's the main reason I chose the 38T as it is that same correction factor (7.3%).
Your 17T is 11.7%.
A 16/39 would be 10.8%

As for the speedo correction, I came back to standard 41T eventually, and have since fitted my bike with a Speedo Healer v4, where you just enter your correction factor and it intercepts the signal out of the box before it goes to the ecu.

My "speedo-healer" is in my head, but I am always amazed at the technology that is available. I began riding British singles in the mid 1950s and have always been used to that nice, slow, steady thump, thump, thump. Modern,high revving engines, although perfectly safe at high cruising rpm, just make me nervous and "edgy", so I placate myself with taller gearing. If I wear out the rear sprocket, I'll replace it with something smaller than the OEM 41T, likely a 38T. Presently, I still find myself looking for another gear above 6th!!

If you want to go 100mph and higher, maybe info us so we can get out of your way, and maybe make sure your life insurance is up to date and paid.
Your new to riding on the street but want to hit over 100mph right away?? You are the ones the bike haters are referring to when they say they are reckless!
