• Trying to work out the top speed of a quad..

Hi guys, I'm just wondering if any of you can help me out trying to find out how fast the quad I'm buying can go. It's an apache rlx 450cc 2010 plate road legal quad with 48 horse power. Not quite sure how much it weighs or anything. If anyone has any idea I'd be greatful. I've tried searching the web and it just says "Top Speed: 48 HP" which doesn't help very much.Thank you in advance.
People who use them on the street have been saying they top out around 65MPH. [editline]4th January 2013[/editline] It's more the gearing than the horsepower, I read about one guy who equipped his with the Supermoto rear sprocket and managed to hit 95MPH.

If you want a higher top speed, replace the gear set for a wider one, but keep in mind you wont accelerate as fast off the line.
I'll have a look into that, what is it I'm looking for though exactly? A whole new gear box or a component of the gear box? Or the sprocket that Bradley mentioned? :)
Sprocket and chain, smaller sprocket means shorter chain (by a small number of links), longer chain if you're going with a bigger sprocket (higher top speed).
bigger front, smaller rear. when I raced motocross, some tracks required more top speed, I used to swap the front 15T for a 13T and keep the rear sproket. The ratio change was enough (15/49 compared to 13/49)
