100mph @ 10,000rpm

'72 CB350F with clubmans and classic cafe' faring.  Tucked my helmet behind faring windshield.  This was after some pipe and carb mods but before cam reground back in the early '80's.

BTW, this is with non-stock front fender with no brace.  Bike was smooth as a bullet.

CB500: about 85mph - never looked at the revs

VFR800: 135mph - didn't dare take my eyes off the road long enough to look at the rev counter!

Sprint ST: 100mph at 9250 (rev limiter) in third gear!
Sprint ST: 120mph ish.

I don't really feel the need to go fast, although both the VFR and the Sprint should do 150ish. 70mph on a good twisty is much more fun (and there's definitely no time to watch the speedo and rev counter!)

Now, now, James. Riding at 45% slower than the posted speed limit is a recipe for disaster in the form of road rage filled road users behind you. That can't be safe. ;)

  • Tryin' To Slow Down "Time"!

           Right about 80mph in 3rd gear, going for 4th (in Japan) on my  "slightly modified" 66' CB72 Honda Hawk. Didn't have time to check revs. Just as I was getting ready to go into 4th, some guy pulled up on the road, quite a ways down, on a bicycle with a bunch of chickens on it and I had to do some kind of shutting that sucker down. Was trying to see just how fast it would go. Ran pretty good for a 250. To date, I haven't really wanted to get up there too much and don't know where I could go, that should be cop-free! ;D

The most interesting was 110 mph (indicated) around 10-12,000 rpm on a rented Honda VTR 250.  Not sure if the speedo was correct, but it was flying.

Well, as a GHOF, I've only had mine up to 75 mph. Seemed fine, but I didn't see any need to unnecessarily abuse an antique, or the bike for that matter. ;D

A tad over 110 indicated on my stock K8.  About the same indicated on my '01 Sprint.  Don't remember rpm, but the Triumph triple does it at quite a bit less than the venerable old Honda.

On this note, I saw something very interesting recently on two bikes from the early 80s.  I wasn't in the US then, but apparently the Jimmy Carter administration mandated that speedos only go to 80 mph (speed limit was 55 mph).  So I'm looking at these two fine examples of motorcycles, a CB900F and a Yamaha 650 twin (the one that could shame Bonnies, in mint showroom condition!).  The speedos only went to 80 mph.  "Honest officer, I was only doing 80 mph.  The speedometer says so."   ;D

Just curious. Where are you folks finding places to do 100+ that are straight enough, isolated enough and with little risk of left/right intrusions? ???

Yep.

I remember seeing a CBX with an 85mph speedo - they must still be around.

Most dual carriageways are deserted early Sunday mornings. If the sun is shining, get out there at 7am and you get at least two hours riding before the mobile roadblocks come out in any numbers.

They don't have to be straight as any decent biking road will have long sweeping bends and at 130+ any other traffic (and the scenery) is coming towards you so fast that your concentration has to focused on the road a good 1/2 mile further ahead of you than normal!

I sound like an expert here - I'm not!  But I have tried it once or twice...

I did the TON on the south 405 on a weekday late afternoon with typical SoCal traffic of the early '80's.

105mph indicated, rpms ~8500-9000 (it bounces a lot). 1975 cb750K5.  I live aways out in the country and there are lots of good spots... I try not to do it much, that would be a hell of a ticket!  Interesting info about the 80's speedos, I had what must have been a 80's Honda speedo on my ride before I replaced it with a correct one. I was always wondering why it only went to 80mph.

The U.P. of Michigan is 99 percent rural. Lots of low traffic roads---but it's the deer I fear.


Why did I do it-----take the high speed risk, punish my beloved bike?

There's several spots west of Denver that are ripe for the ton, especially if you're heading east back toward the city.  Wide expanses of open plain, long sections of highway with no intersections that slopes gently downhill so you get that helping hand from mother nature, and you can see miles ahead! ;D ;D

gordon is exactly right... hmm... who might he be talking about anyway?
actually, i tried it on the 73 cb350f in that area on a ride w/ him and other denver area riders... couldn't get much over 90 that time before i was creeping up on a car.  later that night w/ the gf following on her 88ex500 it ton'd up heading north out of town on i-25... 100mph on i-25 is really not that fast compared to much of the traffic. oh yea, no fender brace and no trouble either.

heading south out of the hoover dam area elizabeth and i came up on a brand new gt500 w/ mexico plates and blacked out windows.  the black racing stripes on white just made me want to have a bit of fun... got up next to him on the 92 zx7r and gave it a few little wrist twitches to see if he wanted to play... he didn't even budge so i just went on around him and elizabeth followed.
before too long he came by doing about 90, i gun'd it and we had a full blown roll-on.  the new gt500's are wicked fast but our speedometer error was incredible.  we stopped at the gas station in kingman and he read 150 while i read 135.  go figure.
outside of pueblo, more deserted roads out there than i've ever seen, before the gt500 incident... the speedo on the zx7r indicated 155 at redline and it got there so fast i know if i regeared it would keep on climbing.  redline = twelve thousand 500 revs per minute... w/ the close ratio tranny it is incredible how fast it can get up to speed... in 3rd gear we're doing over 100mph if we want to... most of the time, we want to  :D

a few weeks ago i found a deserted piece of heaven so i decided to take elizabeth's 98vfr800 to the stratosphere... it had more left on the tach, i think it was around 11,000 or more and indicated 154mph.  i ran out of heaven.  i've questioned whether or not i rolled off because i subconsciously wanted my bike to remain champion... hmmm

yes, i've paid hundreds perhaps thousands in speeding tickets.  yes, i've had a major crash.  am i scared sh!tless when i ride?  yes.  is it because i go fast on occasion? no.  its the old guys in minivans like yesterday that pull out in front of me and two other oncoming cars that made me lock up the rear wheel and get out my bird.  i figure... while i still have these spiderman reflexes i may as well use them... just had to clear that up  ;) ;D

Heffay, that second half of the OBR5 ranks right up there with some of the best rides I've had.  On that stretch we're talking about, I held back for a little while to get some distance before rolling on the throttle and just managed to get the needle to touch 100 before having to slow down. 

That was a good day. :)
