how fast is a 900 custom?

I have a 2011 blackedout 900 custom.I am pretty sure it could outrun anyone elses here, but i really dont know what a 1/4 mile or top speed of my bike would be.I figure about a 9 second 1/4 and 140 mph top speed? Or how about a 14 second 1/4 and 100 mph top speed? We havent had any interesting threads here lately so just trying to get one going.perhaps failing miserably, but we need something new to read.

Bikeless and hating it.

Last time I read anything the 900 was a 14 second / 90 mph (in a qtr mile) bike in the hands of a capable racer.

The biggest issue with performance on the 900 is the top end speeds, it just doesn't have it. Down low it'll pull, and they ARE peppy bikes, don't let anyone tell you different. BUT, they just aren't going to win any awards for speed. There's only so much you can push out of a 900cc motor.

That said, there aren't a lot of stock 4-door sedans or minivans that can do 14 seconds on the quarter! So it's all the fun I need!

If you change the pulleys, you can increase the top end. But, not that I would ever test it..... I think I hit 90 once....

I didnt want speed as a reason for buying my bike.And I have had mine up to an indicated 100 mph several times.I traded in a valkyrie for this bike.now there was speed.I like to cruise/tour at 70-75 and my custom is perfect for that.

140mph might be stretching things a bit. I've hit 105 (indicated) on mine, but that's completely stock so I was probably only doing 95. You're right, you can change the final drive ratio with pulleys and tires, but as you increase the theoretical top end, you reduce the power delivered to the road and you still hit the power vs. wind resistance brick wall; probably at a lower speed. If you need to demonstrate this to yourself, see how fast you can go in 4th gear. Then try again but shift into 5th around 60 mph. You won't be able to hit your 4th gear top speed because you run out of torque earlier. That said, I'd love to try a 1/4 and see what I can do, but I'm not going to push my bike that hard. I like it too much to abuse it that way. When you get a chance to try it, let us know how you do!

My 900 isn't the fastest bike I've had, and certainly not the slowest! I guess you could say it's half-fast; much like its owner.

I would say vn900 is the right bike for the right speed. I was doing maybe 85 to 90.
I think anything after 90mph is pushing it and dont feel the bike is running smooth.
Los Angeles freeway speed limit only go 65MPH. no need to go 90, lol

i had ninja 250 12 years ago only go 75 to almost 80mph, and i have honda VFR 750 about 8 years ago and that thing go on till 150mph, but than i got pulled over and the bike got impounded for like 5 days because it was thanksgiving long weekend.
also suzuki SV650SF, that thing is just about maybe over 100mph, Honda Shadow RS750, only go maybe 75 to 90 before it feels like about to blow up.

900 is a perfect bike for mid weight, and it wont go too fast so you wont get ticket.
it wont go too slow on freeway that people passing you all the time.
I weight about 130 and pretty much the bike can go as fast as it could since im so light.

I got my front pulley swaped out for Baron's. and maybe plan to swap out the rear also from baron's since now they make it available. plus a 240 tire later should help top end speed a lot more with all three element together. But i'm now happy with just the front pulley.

I had a ultra,2 ventures,2 1500 goldwings.the valkyrie was the easiest to handle.But i need forward controls, the cylinder heads were in the way plus i just got tired of the weight.My 900 is light by comparison.
