Top Speed/Highways - Page 3

I have a 2011 gz has 3k mi last week I decided to test top speed for my bike in my riding conditions. I have a regular windshield, small saddle bags and I weigh 215. I made it to 70 pretty quick it was wound tight then I realized I was in 4th gear. I shifted to 5th and eased on up to about 79 according to my speedometer. My gz seems to have a sweet spot between 57 & 65 mph in 5th gear. I'm not sure about the elevation here in Bowling Green KY but I'm well pleased with my little gz. Hope you are too. PS I'm glew I'm about to turn 76 yrs old ☺️

What kind of windshield do you have on your GZ?

I just got a used GZ250 from 2003. It doesn't have a windscreen, and It has a little less power then I hoped.

Full Throttle it maxed out at 115kph (71mph) on the highway, with a little ducking, on a slight downhill. On slight hills it struggles to maintain above 95kpm (60mph).

Is this the best it has, or what should I look at tweaking first? Chock looks great, changed the oil.

Thanks!

You are getting about the maximum from the GZ. I wouldn't expect more from it without major mods. It is not a road bike that can run at sustained speeds of over 60mph or so.

Don't go rushing in to do tweaks. Learn what the bike is capable of doing as designed. A slight uphill will definitely slow the bike a bit. Don't despair, there is a downslope eventually. We sometimes expect a lot from a small displacement bike and that just won't happen in most cases.

The GZ is an excellent small bike that is very popular as a trainer/first bike. It won't try to kill you or overwhelm you while developing your skills. Master your skill for a couple years and ten move up to a larger bike with more zip if you want. You may find that the GZ is all you really need if you don't want to do highway travelling and competing with faster traffic.

When Lynda was still with me she started on the GZ and eventually upgrade to the Suzuki M50. It was a fine bike with both town and country manners. I found the 800cc V-twin to be just right. Maybe it's the old guy in me but too much power and the inability to control the speed just gets you to a crash site first. Even with my Honda 700cc bike I find myself wanting to just twist and go sometimes. Bad idea considering I don't won't heal well if something goes sideways.

I got mine on the interstate quite a few times going 75mph with a top speed of 87mph of course I weighed 107 at the time.

Mine will go 80 mph. Takes bit of time to get there. I have Suzuki windshield that came with bike - 160 lb rider. I also do not recommend mods. Sprocket mod - will not increase top speed. All intake, carb and exhaust mods will net extra 10 mph (if done correctly) and will cut substantially into engines life expectancy. Also will rise chance of catastrophic failure - most likely within head (dropped valves and loosened seats). In case of such failure you are totaling the bike (parts prices are too high to consider repair). Take it easy guys or - want faster bike - buy faster bike.

I've had mine up to 71mph (190lbs rider) on a flat road. Think it still had a little bit left. I'm a new rider but I can honestly say that this really isn't the bike to run at 65+mph on a interstate highway. Sure, It'll do it but not for any kind of long duration. I found that my GZ250 is happy cruising at 45-55mph.

As said by anyone who owns one, its an awesome and nimble little bike to kick around town on, cruise some back country roads, and run some errands on.

My GZ tops out at 60MPH. But then again it's a 125cc GZ But still great for urban riding
