How fast is too fast ?

#1 Unread post by sapaul » Thu Jan 27, 2011 6:14 am

I know what my limits are, in 2007 I hit 285kph on my K1200s and experienced tunnel vision for the first time. I have subsequently been at 250 on a zx10 and reported 260 on a VFR with no effects. My GS does 230 flat out with the wind behind me. I am comfortable at those speeds but I was unsettled with the tunnel vision incident.

So how fast is too fast for you, note I asked for you and not in general, assuming the roads you are riding are capable of handling those speeds.

Don't know, never got there. My old 500 would break a little over 100 mph with my big butt on it given enough distance to get there. The bike handled fine and I felt comfortable but the ole girl just didn't have any more power to give me. So I don't know how fast is too fast for me. :?

I hit 215 mph on a modified busa on a runway in Arizona. I decided overall speed wasn't my limit.

My limit is when my centripetal force isn't enough for my centrifugal force. Stupid Virginia International Raceway.

I don't know the exact speed due to tire slip and not having gauges on the bike, but I've hit a theoretical 167 (rev limiter on a stock sprocket/tire 07 CBR600RR).
My goal is to hit 200 one day.

On my old 1982 Yamaha Seca 650R I did 170km/h once on a straight road and trust me, with 24+ year old suspension, it was too fast.

More modern bikes will make 170km/h seem too easy, the old ones, it is much tougher.

100mph is where I usually cut it off. Bike feels fine at that speed, but this is New Jersey here, so my brain starts doing the "what if" dance about the traffic - y'know, what if that car suddenly changes lanes in front of me, etc, etc. Not really any triple digit roads without traffic around here.

Hmmm, I'm glad I've got a naked bike; built in speed limiter.

I've taken my bike to 170-180kph just to see how she feels. Bike's got no problems, but my chest really takes a pounding at that speed. No interest in doing it on a regular basis.

Short answer, I'd say 100 MPH is about my limit on the street, and I don't like going that fast for very long. With all those insane cagers, the potholes and the cops, forget it. Now a nice long runway would be pretty sweet, but the last time I tried my Tom Cruise impersonation the tower was not amused. My SV only does 135 so that's as fast as I could go on my bike anyway. I'd like to try 170 on a bike sometime just to say I did it. Anyone have a 'Busa I could borrow? ;)

For some strange reason i cant seem to crack the 200kph mark, i have been to 195kph a few times but just cant bring myself to go any further, so as it stands 195kkph seem to be my limit ( for now ) bike feel fine, just the rider has an issue. lol.

I like the Honda company motorcycle. It is the best because it is very longevity. This is the world class.

LOL. So very true. I love naked bikes myself and all of my bikes but 1 I've either had no windscreen to removed the windscreen if it had it. Nothing like feeling the wind in one's face (although I do wear a full face helmet). The neck muscles really get a great workout riding a naked bike on the highway.

With a full fairing motorycle you can easily go faster, but the feeling of speed isn't the same IMO...

When I finally got passed my break-in period on my '06 Z750S I really just wanted to open 'er up... so I did! I was on a straight prairie road and did momentarily hit 170 km/hr but that was much too fast for me to stay at (although I loved the moment!).

In general I don't like to see greater than 130 km/hr on my speedo, and typically I'm within 10 km/hr of the speed limit anyways.

My R850R speedo goes over to 220, :motorcycle1:


when I checked the GPS :oops!:


176 kmh :jawdrop:

But it is naked with a little screen and does appear to go faster than it is, plus it is loud as hell.

Speedo Error:

On my Suzuki DL650 V-Strom, it was off 8%, from what I know if it's off by more than 10% you can take it to the dealer and have it fixed (for free) as by law it can't exceed 10%.

Ha Ha, you made a funny Mike. Little things like that just don't apply here. That's like telling the Nigerians that they have to wear helmets. So every day they eat their water melon and make two new ones. In my case BMW would have no problem fixing it, but man, the bill would mean I would have to sell my house.

Even though the GPz900R was only capable of 150MPH I was able to take it to 160MPH (GPS as the speedo cable had broken a while back) with some throttle/ revs left. I think the guy who owned the bike before me modified it more than I knew about but it fuels perfectly and is steady until 130MPH (no vibrations or wind pressure).

I've been up to 125mph twice on I-10, both times were to get away from idiot drivers that I felt put me in danger. I accelerated heavy on the R1, got away from the unsafe situation, and then slowed back down to a reasonable speed. That's with a speedo-healer on it, too, so I figure that's pretty close to spot on.

I'll do 100mph fairly often when there's no traffic or very light traffic, but considering that most traffic flows around 70-80mph I don't feel that I'm putting anyone at undue risk and will slow down if traffic picks up. While riding back to Tucson on Christmas day 2009 on my 636, myself and a car were doing 95-100 almost the entire way from Phoenix to Tucson (107mph indicated). I stayed in back and that helped to alleviate much of my worry about being cut-off or not being seen as I approached traffic. We had to slow several times for traffic, but as soon as we got through we were right back up there again.

There was a sticker available to correct it years ago (from a 3rd party on the net) and a corrected speedo plate (again 3rd party)... I don't mind the speedo saying faster as if I'm doing 5-10km over the limit as least I'm not speeding... haha.
