Change gearing to lower RPM at highway speeds

    Hoping someone can help, I have a Yamaha 650 V-Star Classic. I read somewhere on the internet that by changing the gearing I can lower the rpm when I am at highway speeds of 70 mph so the engine is working less and reducing the vibration. I am aware that if I change the gearing to make the engine run slower it will also make it more difficult to start moving from a stop. If anyone knows or has done this modification, what are the gears that need changing and to what size? I am hoping to hear from someone who has modified this way and were the results worth it. My bike is already stripped down for other reasons so I thought now would be a good time to change the gearing, or am I better off just living with it as is?

    one thing to think about is this. If you change the gearing to lower the RPM, its going to also change how quickly you accelerate. It will end up taking you FOREVER to get to 70 mph

    this engine is built to run those rpm's anyways. This bike loves to cruise at 70 mph. with the stock gearing. I'm not even sure there are any kits or anything you can get to re gear anyways. It would be a different story if it was a chain and sprocket drive but having a rear differential and drive shaft set up is a whole different ball game. Gotta remember this bike is i think 32-35 hp stock, gearing it up like that would make a noticebale difference in your power and acceleration all the way across the board. Live with it and learn to love it, its pretty fun running that little engine on up in the RPM's. It actually seems to enjoy it if thats possible lol

    Welcome to the forum. You are not hurting the bike at all by running it at high RPM's. It is built to run like that. There are guys with many many highway miles on their 650's with no problems from the higher RPM's. Just get used to it and in no time it will feel fine at 70-80mph.

    After reading all the responses I feel comfortable leaving the bike as is. I greatly appreciate all your input. It helped me make a final decision.
