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

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)

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.

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.

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

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)
