Post your 1/4 mile times

Went out for a bit of fun last saturday.... didnt change anything on the bike from my normal setup, 32psi rear and hard suspension....

Rode out to willowbank raceway...50km ride...

10.839 sec at 129mph....

with a .624 reaction time(.400 is a red light) 1.8 sec 60ft time

sorry that i bailed on this outing... uni sucks

I also have an idea for getting you a little bit more clearance in the airbox in the mean time (before we start working on the new seriously big air box with variable length intakes).

10.60's are quick for a street bike...

With the duke the more i kept the front down the faster i went... i did a 11.2 with the front in the air through second...

I only hit full throttle at the end of second... i think a shift light would have done a world of good too...

We have a sprint here with an s bend in the middle! I lent my bike to Fast Bikes Magazine last weekend to do it. He was going cautiously but I think he did a 11.35 or something. Slightly damp.

that sounds cool... and perfect for the duke

Thanks for the details..... I have this problem with an over enquiring mind

I will get back on the strip with the SD in the Spring time, would be good if us UK guys could organize an SD meet at Santa Pod, drag racing is just as much fun as a track day and gets real competitive if there is a group, you get to keep your timing slips to

Could turn it into an international SD Forum challenge UK v USA v Aus for the fastest 1/4 mile SD/SDR

Just a thought

Them sound like fighting words Russ...

Yeeharr... Challange Accepted

Rules??

May I sugest a photo of the time card and a pic of the bike with the number on it.... Too much??

...And... a bull shit call... if you post a 9.245 ...ill call bull shit...

ill post my time card tonight

the first blow to Australia 10.839 @ 129mph

this is awesome.... there are 2 Test N Tunes every week in brisbane Australia.... $45 a night of racing

Now... Were is the thread for a NOS kit

Looks like its only me Vs the Aussies then........

What a bunch of pussies...............

I'll join in but our 1/4 isn't straight.





videos are from an event where I managed 11.35 quite a while ago, the 05 only had cans and map on it.

Missed a few events due to an accident but the new bike is much quicker, did a 11.26 after shutting right off from running REALLY wide and then we were rained off. Can get into the 10s easy next year

Nice...

looks like mad fun

Sweet! Can't wait for next year (April 28th) . Something about a 1/4 mile that gives a huge rush different to that of a trackday, especially with a fookin S bend in it!

I finally made it to the strip, was fun but got rained off just as I was getting the hang of it.
This is on Standard gearing 17/38 you can see my 60' time needs BIG improving.
If the weather is good next week, I'm going again... I want the 10

We measure 64' over here for some reason. Best I managed was only 1.96, will focus on that in a few months...

Extra 4 feet is 1.22m in english

Into the 10's!
Well I got some sweet reaction times!
Won $150 for a 0.001
In the last part of the night the light system changed and I got 2 <-0.400 now I wasn't fouled out like when you jump start and I still won.
Can you explain these for me Indy?

fook yeah 10.8... fook these dukes are quick... r1's are 10.5 with a good rider.

its the original start system is .400... its the actual time it takes for the light to reach your eyes... its phyisically impossible to see the light before .400 of a second and therefore classed as a red light... as there is no way you could have seen the green light before you launched.

the new system deducts the .400 straight away....

How did it come off the line???

i rode 1st gear half throttle and pinned it in second gear to keep the front end down

the other thing i noticed is that your doning 125 mph and im 129 mph ... thats alot for such similar times

Linga,
Which SD do you have the regular model or the R? What mods do you have? Getting into the 10's is damn impressive. Congrats!

5th to 6th
Only second time at the drags so not sure where the finish is exactly

You can see the difference in terminal speeds on these two similar runs...
I wish I had a good reaction time on the bottom one... 10.4...?

My best terminal speed is 123.58. As well as having the HP surely being 70kg with gear is a help also.

How much do you guys weigh?

76kg .... with pants on

Well you did better than I did! Think my best was 11.68 @ 118 odd mph. That big spin and slide on the first run really didn't help my confidence. But that's no excuse, just didn't really happen the way I'd hoped. Always next time.

Maybe next time try running on the wets!

Here's one of my better runs...

Whats your gearing, 16:40? Bike has quick shifter? Slipping the clutch at 6K rpm is the best way to have best "launch control"? ...how do you comment ...and thanks for sharing tacho, I still have no clue how to go right on and right fast from stoplight; seems 0 - 30mph is just not this bikes playground

Yes the gearing is 16:40. No quickshifter at this point. For me around 5 or 6k feels good, just under the peak torque but this start isn't very good. I was too slow in getting the clutch to a good point and I rolled off a little too much through the corners. Plenty of room for improvement in September!

Should be coming soon..???
Looks like a blast..
but why don't they pick a straight
road to run it on.???
Just curious...

Hey sorry for being late to the party, didn't know there was a Super Duke drag race challenge. I guess I'm the only U.S. SD drag racer so I'll do my best. I just went to the local track last night (Wednesday) with my '06 Super Duke and already ordered a 16-40 sprocket combo from just 5-passes down the track. The bike is all stock except for an Akrop header and a pair of Two Brothers one-off proto cans, (2-Bros used my SD to do the fitment and let me have them ) Also stock intake and paper filter with 17-38 gearing . So not knowing this thread was going on I started one today and then TLS_Russ and Linga let me know about it and Linga posted the link, (thumbsup and beers )



This is what I posted in the other link: (and how do I post my time slip and a photo of the Super Duke)

NE1 1/4 Mile Drag Race their Super Duke?

by SUPER DUKE #1 » Thu Sep 06, 2012 3:30 pm

Took my Super Duke to a local NHRA drag strip for Wednesday "Fun Night" just to see what kind of times it would run. The bike is basically stock except for a one-off set of prototype Two Brothers cans with an Akrop ti header. It ran 11:404 @ 121.69 MPH. The rear tyre NEVER hooked up (too new and too rounded, need a worn out flat tread area tyre that we all throw away ) and would spin even with the front wheel off the ground. Hit the rev limiter a couple of runs that killed a chance at a little better time but "that's racing". I hadn't been to an actual drag strip in many, many years until last Wednesday when I took my '69 440 Plymouth GTX (4-speed) to the same track. They had over 50 bikes there last week and I thought the bikes looked like they were having way more fun racing and shooting the $#!T between runs than the cars so I decided I'd take the Super Duke last night. It was a lot more fun and ended up hanging out between runs with just about everyone of the 40+ bike guys there and ran the guy that won eliminations last week on a 2000 Aprilia RSV Mille running 10:70's several times. He was really interested in the Super Duke and little did he know that the same engineer Claus Holweg that designed his engine at Rotax also did the LC8 for KTM Could go on and on about last night but I have some tweaking I need to do to get the Super Duke into the 10's, stock with nothing more than a pipe and cans.

Anyone else drag raced their Super Duke......what kind of times?

This is the track's report from last Wednesday with a photo of the Aprilia that won.................(and a photo of my '69 440 GTX, yellow with black vinyl top and hood stripes). I'm out to whoop some Aprilia butt with the Super Duke so I'll need lots of help from you guys THANKS!

The guy on the Priller looks like he has got the front end strapped down

Yeah there's only about two inches of travel showing and the rear is lower too. He trailered the bike there so the set-up the same evertime and he's got it down to a consistant dial in time of 10:70 or 10:67 depending on conditions. Me, I'm still all over the place right now 11:404 to 11:712. I'm going for 10:6's and Aprilia hunting Time for the carbon wheels with a flat center race compound 180 slick, what do you think?

Went again last night and only got two time trial runs in. Used them to try different shift points closer to peak torque from the dyno pulls........that worked like crap The only change from last week was the rear sprocket was changed from a 41 T to a 38 T. Came off the line well shifted around 8,700-9,000 and went backwards to 11.810 @ 122.13 mph from the 11.404 best so far.

Next run upped the shift rpm to around 9,100-9,200 rpm and went to 11.646 @ 122.52 mph which was a little better than the first run. Then it was time for eliminations and who lines up next to me but the first two event winner that was on the Aprilia but he's now on a Busa with a dial in of 9.80 I dial in 11.40, stage, let go first for higher dial in of course get to the finish and he comes by AFTER the line and I have the win light glowing in my lane. Find out from him picking up the time slip that he spun at the line and he says "I can't ride this thing worth a crap". I run a 11.584 @ 121.20 to his Busa time of 10.468 @ 141.11.

I figure that with my next run against a Kawi 4-cylinder, streached out laid down, drag purpose built bike with a dial in of 11.69 that I would dial in a 11.50 which was a tenth slower than my best of the past weeks......didn't want to red light so I pull a safe launch and go .404 R/T and then reel the Kawi in about half track, go by him, he gets on the brakes pretty hard 3/4 of the way down and I'm thinking he has a proble (that should have clued me in) wait just a hair longer and roll off the throttle hard just before the speed trap and his win light goes on I run a 11.457 @ 120.11 mph with a 11.50 so I break out by .043" It was in the low 50's F by that run and the bike was running better than ever so I now know I'm mapped a little too rich for the early part of the race and sure would have liked to have gone and run another time or even a time trial as that felt like a 11.20 or even a 11.10 running Super Duke. May remap it leaner and head to test and tune night tomorrow? Oh and I was back to shifting at or near red line on the tach oh and laid down but not Joe Kopp style....yet or until I grow a bigger set

I found these photos of me and "borrowed" them or just moved them over here Always the odd ball with the strange "what kind of bike is that" so someone was always watching.....chicks were digging it (made that up )

Get them fooking mirrors off

Get them fooking mirrors off

Get them fooking mirrors off

Sorry......... back on a rubbish Apple computer as you can see

Okay I'll try and lose the fooking mirrors the next time!

Okay I'll try and lose the fooking mirrors the next time!

Okay I'll try and lose the fooking mirrors the next time!

But I ride to the track and the trip is through an area were there are a lot of State Highway Patrol officers and a lot of local Sherrifs that always check out bikes especially guys in full leathers and loud pipes.

Now I have to bring tools to take them off and then put them somewhere near staging,

Ever come off the line in 2nd gear with 16-41 or 16-38?

I've been using 1st and carrying the front wheel just slightly but I have to shift it so quick that I'm thinking of trying 2nd tonight.....what do you think?


Another "borrowed" image

Forgot to put the shield down on my first run that night but with no dirt or dust not a problem and eventually the wind at 100 mph puts the shield down for you anyway

Went 11.184 last night, so close to high 10's I could kick myself. Only one time trial run and then right into eliminations and got beat after two rounds by a 9 second Kawasaki that dialed in a high 10 and just toyed with me at the line. Now I have to figure out if I should play that game or just run balls out ALL THE TIME? This guy is a regular and has been doing this for a long, long time and told me that's what he does, he reels you in and then beats you by a wheel <-- that's me mad at myself for letting that happen. Have to figure out how to make that "wheel" that he put's on you at the line to make him break out


Oh and I put on a quick turn throttle and that really helped! I get FULL THROTTLE quick and ALL OF THE TIME. On a couple of runs the weeks before I was in a position on the bike that I was not sure if I had the bike WFO now I'm sure! I think this may have helped, in fact I know it has helped with 2-3 tenths ET. It's the Power Parts quick(est) ratio aluminium throttle tube, not the one with the three different ratio but the single ratio. I'll get the part number if someone wants it?

11.103 129.72 mph. 2015 SD with -1 front sprocket. I know the bike is capable of getting in the 10's, I just need to work on my launch keeping the front wheel down.

Anyone know or ever compare a standard 990 Super Duke quarter mile times and speed to a 990 Super Duke R? Any guesses? Have a chance to swap my 990 std. engine for a new "R" engine and wondering if it would be worth the effort? Thanks.


SD#1

Well, I don't have any 1/4 mile time, but I did a few 1/8mile runs in the summer. The best time was 7.01 sec @ 176kmt. Full akra exhaust, otherwise stock bike.
