Rider's weight and acceleration?

Just as you might imagine, the bigger the bike, the less your weight matters. A 700 lb. Harley Davidson won't even feel a 230 lb. person (but then Harleys are not hot bikes anyway). On a 200 lb 125 you'll really notice it.

Most motorcycles accelerate faster than most cars anyway. And most bigger bikes (bigger than, let's say 500cc) are made for a 175 lb rider and a few pounds of baggage. I would say anything bigger than 500 or 650cc, the difference made by your weight would not be noticeable.

Of course the more weight on a bike the slower the acceleration will be, that's just physics.

If you want to go faster you will need more horse power.

The other thing you need to consider is the bikes suspension. Like on a dirt bike the rear suspension can be set up for a heavier rider by selecting a stiffer spring on the shock.

For a guy of your weight I would recommend nothing less than a bike with 80 horse power.

Extra weight takes extra HP and Torque to get moving and keep moving.

Yes, it's more of a factor with lower HP motorcycles as they don't have a lot extra power to begin with. A 1800cc Goldwing isn't going to feel an extra 80 pounds as much as a 250cc Ninja or even a 600cc Ninja.

If you are going to ride two up a lot, then being larger yourself and adding a passenger is really going to affect a smaller bike a lot more than a bigger bike.

People on sport bikes keep trying to shave weight off their bikes, when losing 10 or 15 pounds off themselves would be cheaper and more effective plus healthier for themselves.

I have 3 different bikes. A yamaha 250 v-star. A triumph America. A 750 Kawasaki Vulcan. All bikes excelerate differently when I carry a passenger. But, the 250 is affected the most noticibly by the extra weight.

The smaller the bike the more difference weight makes.

For big men V twins have more Torque for pulling, a 600/4 sport will not ride around town as well as 600/2 cruiser.

The lighter you are the faster you can go...

To get the equation figure out the weight and horsepower of the bike in question...

(weight of the bike + 30 lbs fuel and fluids) + (your weight + 15%) / horsepower.

My SV650 and me

320 lbs dry weight + 30 lbs fuel and fluids + 200 lbs me + 30 lbs Gear / 84 hp = 6.90 lbs per 1 hp

BMW S1000RR and me

410 lbs dry weight + 30 lbs fuel and fluids + 200 lbs me + 30 lbs Gear / 193 hp = 3.47 lbs per 1 hp

Too general to answer. Best check on the bike's spec for your answer. All bikes have weight max limit.

For the bike you are looking at, asked or search of the bike's info and spec. There should be a maximum weight. There is no standard weight. Anyway, good to ask and know. Good luck. Enjoy your bike.

Unless your talking very small cc motorcycles below 250cc its not going to be that much of a factor. If will affect if but not that much.
