There is no fixed law that says that you have to change gears when you're at the max rpm, or that you have to change down when you're at X rpm. You should really start driving solely by what you're feeling, and not be fixated by the numbers. Should follow the speed limit and such thou, ofc. Lyoko - Black Rebel 500. U.
They're a lot more similar than people expect. The seating posture and fuel tank are really the biggest differences, but they're both nimble and responsive bikes. The Rebel feels like a CB500F pretending to be a cruiser rather than an actual cruiser. The CBR500R is a CB500F with more bodywork and clip on handlebars. Rebel 300- 85mph. Rebel 500- 105mph. Now like I said, these are estimates and will slightly vary depending on where you live since altitude can change performance. These bikes have the engines from the cbr300 and cbr500. CBR300 top speed- 97mph. CBR500 top speed- 116mph. Now the Rebels have the same engine but they are done a bit different.
