Curious on your guys top speed it seems as if If I'm doing 70 to 80 it's about topped out reving pretty high is this normal or is there something wrong? P. S.  Yes I'm in 5th gear oh and I rejetted and put on cone filter and new exhaust

I have a stock 2002 and it'll cruise at 75mph.  80mph is the highest I've had it and it seemed like it didn't want to go much higher.  That's with all of my 220lbs.

If we only had 6 gears

90mph stock and not kidding 2nd week I got the bike took off after work one night and did 90 all the way to Joplin, Mo about 1hr and half drive there. No other cars on the freeway till I pulled into Joplin. Even hit up to 95mph on the downhills.  Lucky me the next day I noticed the saddle bag bracket bolt on the inside of fender was bent in towards the tire. I had a 1/4 deep groove all around the new tire.

Some stock bikes will top out between 85 to 90 mph, more likely about 87mph. This may depend on tyres a little, we are told the 140/90 15 will make the speedo more accurate. What happens after "tuning" "remufflerisng" and "jetting" could be any bodies guess, sometimes these things help sometimes they don't.

I got up to 94mph... on a long stretch, trying to catch my friends that took off on a ride I thought I couldn't make...
Never caught them...
... and 94, is not a speed you want to go on this bike for more than minute or two...
...(my bike is slightly modded, I'm 145lbs, and I was tucked in like paint)... (/90 rear tire is fairly accurate,.. super dry air here helps)...
Suzuki says 88mph top...

I did finally meet up with them, 75 miles down the road at a cafe'...
Since then,... I've never pushed that hard...
I can hit 85 pretty easy... that's good enough...

Can't afford the ticket anyway... ...


Gearing won't help... you can hit top speed in 4th gear....
It takes more HP to top out 5th...
If you can't hit 80mph,.. your mods have reduced power...

My completely stock 2013 hit 93 once down a slight hill. It wasn't so comfortable! 75-80 with ease however. 70 down the interstate is pretty comfortable, except for knowing you have little juice left should you want speed up.

I've been debating on 0-60 time with my buddy - I think it's faster than 8.7 seconds but don't have a radar gun to really determine.

Since all 2-wheel speedometers are inaccurate, I installed the Ulysse GPS Speedometer on my android phone to see how fast my 150cc scooter would go.  It's a pretty cool free app that will record your top speed so you can leave it in your pocket and just check it later.
When the speedo on my scooter shows 65, my GPS speed is 60.  That's not bad.
I'm gonna check my S40 with it, too.

Motorcycle speedos have to be 'optimistic' because it's against the law for a speedo to read slower than your actual speed.  And since bikes use the edges of the tires and not just the max diameter, speedos have to read 'optimistic'.  That's true of speedos that read from the front wheel, anyway.
