06 SDR Chassis Geometry

Can anyone tell me were i could find the chassis geometry numbers for the early model SDR?

Also, what was the spec of these bikes and differences between this and the standard 05? There dont seem to be many of these bike about from what i can see.

I'm currently ball deep in setting my bike for this years track season. I'm not really prepared to go into the changes just now, but i have a few goals set this year and if it all works out i'll gladly share. We all know though, one man's sweet bike setup is another mans nightmare. I know what i need from the bike to get it where i want it. It's just a bit of a battle to get it there.

The problem i'm finding is alot of the info out there is for the 07> bike which pretty much has the desired sweet chassis numbers to start with. The later SDR has the same numbers as the standard 05 bike but acheives them it a completley different way. (SDR through shock, 05 SD through yokes)

Standard 2008 Superduke -------------------- 2008 Superduke R-------------------------------------Standard 2005 Superduke

103mm trail------------------------------------94mm trail-----------------------------------------------94mm trail
23.9 degrees rake-----------------------------22.7 degrees rake-------------------------------------- 22.7 degrees rake
swingarm angle ???degrees-----------------swingarm angle 7 degrees------------------------------- swingarm angle ????degrees


Gerry Piazza's numbers on a good starting point for chassis geometry on most bikes would be:

104mm of trail
24 degrees of rake
10-11 degrees of swingarm angle

From what I can remember the SDR first came out in the UK in 07

Might be you cant find spec`s for an 06 SDR

Pedantic ole git.


Ok, it's the early model SDR. With the big old style mask. Like they used in the 1st Battle series.

The first battle bikes were just the standard 05/06 SD's but with reworked heads I think and the single seat.

See, that makes sence. It would explain the Battle Edition like Jody's.

When i was scouring the dealers looking for a bike a while back i kept getting told there were SDR's in the early model but the majority i'd find would be ex race bikes.

So the 2007 series was tuned early models and 2008 late SDR's?
This would be early bike cadwell times...... (runnning control Conti Race Attacks)


And this would be late......(running Supercorsa SC1)



2007 series


2008 series

OK il try and shed some light!

The 2007 SD cup was just 2005/06 Superdukes with a carbon nose cone and seat hump. Conti Race Attack control tyres as you state. Engine and suspension tuning was allowed with the front runners choosing gas flowed and skimmed heads, modified standard airbox, Akra end cans and PC3 custom mapping. No other mods were supposed to be allowed but Dave Woods was well known for stretching the rules

The 2008 SD battle bikes were based on the latest 2008 Orange framed Superdukes unmodified apart from suspension reworks and end cans/KTM mapping running Pirelli Diablo Supercorsas SC2 rears SC1 front control tyres. (The new rubber is what most people believe achieved the lowering of lap times in the 2008 season).

The original Superduke was born in 2004 and became available in 2005 and continued into 2006. The Battle addition was just a marketing tool by KTM to shift a few more SDs off the back of the race series, mods were nothing more than a fancy nose cone and single seat unit. Youl find there are a fair few original SDs floating around on 2007/08 plates as dealers couldnt shift them so they stood on showroom floors etc heavily discounted till they all got bought up!

In 2007 KTM revised the geometry and gave the bike a facelift and softened the engine characteristics a little.

2007 also saw the 1st of the orange framed SDRs, these again had revised geometry to suit the R nature but the engine was still just a standard 120HP SD lump.

2008 saw the revised SDR but the only revision is the engine. Chassis remained as the 2007 SDR and still remains to this day.

All current standard SD still have the same geometry as the 2007 standard revised SD.

with all the effort you are putting into this viking , i expect to see you flying past me at crashfest.

I like the technical stuff. Nobody ever said I was fast. . I'll give you a run at a wheelie contest though.
Chances are it'll be upside down again before Crashfest so it might not even make it there.





Stew, awesome info. Cheers.

Only thing that's stumbling me is the 05 numbers you posted. I can't believe they're the same as the 07. Posting from my phone here so can't get a link but every stat I found shows it with the same numbers as the 08 SDR. But our bikes get it through the triples, hence the differences and me having to buy the 08 lower to make he Nichols fit, and the 08 SDR does it through its long tear shock.

I've ridden an 05 and 08 back to back and the 08 is definitely much more stable and slower steering.

Bash. We need a "like" button on here.



I like your style Russ. That wink smilie always gives me a chuckle.

Good info guys. Cheers again. A man is only as knowledgeable as the info he receives. Back at the start 2 dealers told me there were early SDR's, I've never looked back into it so took it that was the case.


Keeping it simple, the outlne is...................

I'm a master tech to trade so interested in how things work. I've never been happy with the feel of this bike. I've tried a few different riding styles etc, even running it through duffus and clarks at knockhill almost with my finger tips on the bars to see if if was my grip. It feels vague from the front, and i noticed compared to other SD's it never really built front tyre temp as well as i wanted or compared to other SD's i met on track. I've tried runnning it through harder on the front and it starts to tuck. Twice they were small and it came back instantly itself, the last time it didnt.

The forks were shagged so doing them alone might have been enough to get it right. I just want the bike to feel as i want it. Then i'll be comfy lapping on it.

I might go out and still be doing 2min dead laps at Oulton, doesnt matter, the bike will feel different. If you look back my posts you'd see i never talk about whos fast etc, It doesnt matter. I like being on track and feeling things working under me, making changes and feeling the difference they make, thats the hobby for me. For me it's about me, the bike, and the track. If i could lap away myself on a trackday with no other bikes out there i'd be happy as larry

I've saw the sags the battle bikes were running and can see what they were trying to acheive by it. Now i've got a gps timer i've got a little personal goal to go out and try and get a decent grid time to match the battle series. They ran shite tyres, but i'm a shite rider so it all evens out.

Even if the Nichols doesnt work i was getting off just looking at it. I'll put it on the mantlepiece.

Yeah, I would like to get me one of them Nichols Top triples made up for my 05 as you say just for looking at is a good enough reason
and being able to push the forks down another couple of mm, solid mounting for the bars, more feel mm,mm,mmm, close to perfection I reckon

Maybe when you crash it next I can buy the top triple off you cheap and get it copied in the UK with 05-06 offset

I'm sure they were bud. They've got to have been with those times.

From what I've seen searching back TDR threads a low 1.40 is top end of fast group on a trackday (depending on the quality of the group)
