I wanna get ton'd up on Cassandra... the bouncing in the front tire is stopping me.  Will repost top speed when I address bouncing.....

To date, 90 mph @ about 7500 rpm - 1975 CB550K.....  several times....

Cassandra's nickname has become T-10 (T minus 10 AKA Ton minus 10 mph) due to the bouncing.....

Tad over triple digits.. :o 77 750F2

Wide open land, see for about 10 miles straight ahead, no intersections or cars or trees to pose deer hideouts. I was cruising at 70, rotated the throttle to close to half, the bike started to feel lighter saw that I broke the triple digit and I let off of it. Bike has new tires, tubes, all new bearings, chain, sprockets, and it did it without breaking a sweat. I usually cruise between at about 60-70mph on the open road.

I did it once to see if the old girl still had it in her, it did it with no problems. I much prefer to cruise on her though.

  • we're out here and this is where we are.
It must have been 'ride to work' day. Got on 580w/b and ran the T350 thru the gears. Not even trying to go fast. Had most of the tach left. Approaching the maze, looked at the gauge - wavering in the 95-100 area. Let off so fast, I'm surprised the wheel didn't lock.
As the speedo dropped under 60, a CHP Dodge Monaco (that had apparently been pacing me) shot by like I was standing still.
Took the Berzerkley exit and watched The Man go to S.F.
Seeya!

1974 CB750K4 riding on the German Autobahn going flat out and speed indicated at 110mph in top gear, 8000rpm or so (wasnt really looking at the rpms too much  ::)) - lucky the road was straight and I had a lot of stopping distance. Felt like being on a missile ;-)

cheers

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?

You should come to Maine!

I've been out and about at 90 pulling just under 8k on the tach.  I was on my morning commute and trying to not really push it.  My Vetter SS makes the mhp easy on me and my 78 750F has a lot left in it.    I'll pull the ton before the end of summer.

You can't make too much popcorn, but you can definately eat too much popcorn.

hmmm....don't remember the revs but was only in 5th gear (6 speed gearbox) and was no wehere near redline and hit 190kph so guess that would be around 115-120 mph. It was last weekend on my CBR 600 around Port Dover after we left due to it being WAY TOO crowded...

  • Bought her new 4/75
1975 CB750F

Circa 1975 while bike was still newish before I blew it up. Nice crisp night approx 1am after leaving the bar (couldn't walk very well but I could ride - youthful foolishness) I topped a rise on a 4 lane road and nailed it. I was viewing the road in front of me from the slight opening between the tach and speedo while hugging the tank. I glanced up at the speedo with my left eye and when I saw 125mph I decided I was too drunk to be riding, slowed down and went home. I was amazed at how quick it got into the redline in 5th. Didn't take a look at the tach but it was in the redline somewhere above 8500rpm.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

 I was riding my 1985 Honda 650 Nighthawk at US 30 Dragstrip in Merriville,Ind. I turned 105mph @ 13.06 seconds. I didn't notice my rpms but I wasn't close to redline. Got a trophy in my ET bracket. I put down a 13.00 breakout time. Best running bike I ever owned, should have keep it.

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? ???
In Illinois, I did the "TON" on rte. 20, just west of Elgin, Illinois.  Was 125mph++ at redline 8500 on the mostly stock '76 CB750F.  Was a straight enough section of road, and it's a limited access route.  The really dumb thing about it after I slowed down and my brain was able to catch up with me, is the State Police District headquarters is only 2 miles back  :o.  They would've killed me in fines!  Got 'er up to speed, held it ther for about 10 seconds and backed off.  Was fun, but not something I'd really care to do again. (the guys with the crotch rockets are reading this and laughing......."125????  Pffffffft! that's when I hit 2nd gear")

If anything breaks - you're dead.
If you get nicked - you're banned.

'82 Kawasaki LTD 1000 - about 125 at 8500 RPM (calculated speed by rpm since it only registered 85 on the speedometer) Lots of wobble above 105 mph
'82 Honda V45 Magna - would do about 125 in 5th gear but not sixth.  Redline was 10,500 but would pull waay past in 5th.  This one was a wobbler too.

Sometimes you could dampen out the wobble by pushing on the handlebars or lifting your bottom off the seat to put more weight on the pegs

'74 CB750 stock - about 110 - didn't look at the rpm, but probaby about 8000.  Ran pretty true and straight

I mostly did mine at night on fairly empty roads except for my brother who was usually right beside, behind or in front of me on his Magna.
