Yippee......was at my KTM dealership today, tracking down some NY sales specials, and asked about a steel 40T sprocket........expecting the usual glum looks.......but wait a minute......there's a supplier on screen, no pic, but fuggit I've been that desperate for so long, I put my $45aus down and will have a shiny steel 40T in mid Jan :D

Of course not everything goes to plan - they didn't list a 39T, so that'll have to wait a while - my evil plan was to have both so I could tune the gearing to my roads and of course the new tyres (PR4) when they are due - but a 40T is a great start ;)

Dave, any chance of a part number or supplier reference for the 40 T sprocket?

I got mine off eBay, 40 tooth steel-black, from Germany from memory. Last time i looked, they were still advertizing them.

Cheers SuperDukeGT......the sprocket on order from my local is a Supersprox.

Sorry to Thylacine.......this forum is a bit odd - gotta go searching thoroughly to find new posts.....

I saw the Euro suppliers that Dave NZ was writing about - they had either Japanese high quality JT brand or a high quality Euro brand available (can't recall the brand name), but at the time the deal was for Euro customers only, then I found I couldn't order them as there was an Aus agent...... arrrgh......and the agent wasn't interested in bringing any stock in.........maybe they have seen the light and brought a container load of sprockets in now - try Metalgear...... in any case I placed my order with my local KTM dealer as they had a source of steel sprockets in their system.

Otherwise, hit SuperSprox up and order from the USA.

Cheers all.

I live in the states so what I’m seeing on here I should get the 40t rear and not the 39t? I would love to use 6th gear on something other than interstate

Since changing to a 40T rear sprocket, the bike rides tremendously better. But I still don't use 6th unless I'm on the interstate going consistently faster than 75-80 mph. So I would not go to a 39 if I were you.

Agree, the Steel 40T/525 pitch Rear sprocket is a great improvement in the KTM SDGT for street/ twisty riding in the USA. Highly Recommend!! Best,

Yep, 6th gear cannot be corrected with a simple sprocket change (no room for a 47 tooth eh? and that would ruin the 1-5 ratios :roll: ).....check out the revs when holding say 60mph in 5th and then slipping into 6th - it is a huge drop in revs - last time I looked I think it was about 700-750 rpms difference....... so 6th will still be a ratio for unmentionable 'touring' only.....but at least might be usable on down-wind or down-hill highways. ;)

The 40 tooth reportedly gives about 350rpms and the 39t about 180rpms (cheers Dave NZ & Mr C)......which won't affect the existing the 1-5 ratios as the motor loves sitting around 4500-5500 anyway, so instead of 4250 in 5th at 100kph (for me) my GT should do approx 4600 or so with the 40t (at 100kph).......yet to see the sprocket.......it's still coming .... :roll:......like cooler weather...... :lol:

Now having the 40 tooth rear sprocket, i regularly use 6th gear, anything over 110, its ok to cruise in, i did the O2 sensor removal, and this helps with the lower rev smoothness of the engine.

I got the O2 sensor eliminators as well before I got the bike, but I find it very smooth, so I haven't bothered to install them

A week after me buying my GT i binned it, sliding down the the right hand side :cry: , so rather than replacing the exhaust with the origonal, i fitted a remus and link pipe, did the SAS removal kit, and then the O2 sensors to make sure it wasn't running lean, then did the 40 tooth sprocket, all while my ankle and left wrist were in a cast. Im happy how the bike runs, it feels smooth, and runs the smoothest (fueling) in Sport mode.

That link does not show a 40 tooth sprocket. It says N/A when you click on it which implies to me they don’t offer it, but I suppose it could be just out of stock.

Wow! That set of Black 40T/ 525 Steel Rear sprockets for the KTM SDGT must have sold out quick. Popular conversion. Consider giving Craig at SuperSprox a call at 800-328-5454 if you want one to see when the next shipment will come in for sale?? Best,

Doc :? :?

I may do that....when I get my bike. I found out yesterday it had not been shipped from the distribution center yet. They said it should ship today and hopefully be here next Tuesday.

I'll be playing bike mechanic this wet weekend :lol: and am looking forward to testing asap... ;) (every ride is a test ride right ?....)

Arr, that grey part of the pic states C-45 high qual steel, long life anti corrosion silver finish, and carbide cut cnc machined teeth..........looks like a new OEM spec sprocket to me.......roll on Saturday (too much traffic going past on a Friday arvo to bother doing technical stuff...... :roll: ).

This is what my local KTM dealer spares ordered for me, $45Aus, so your local should have similar contacts (nobody knew anything 6-12 months ago......now there are lots of things readily available....check out the Vstream windscreen post I spotted earlier on the forum.......trick, good looking, functional.....wow!).

Some talk above about changing front and/or going to 41 or 42 teeth - don't do either.....DaveNZ and Mr C are the 'go to guys' on this one.....so the 40T is the go (6th is a lost cause as it is just too big a rev gap to ever bring it into real world use without stuffing up the near perfect 1-5 ratios ;) ). I might try a 39T later, if I think I need to fine tune after using the 40T........but that's not a huge priority for now.

Hi all,

I knew it didn't take long but holy cow Batman, that was bloody quick and easy :!:

One thing...... the pretty side of the sprocket goes to the inside......to keep the chain aligned with the front cog.......not sure from the photo, but Gary's sprocket may be installed incorrectly... :idea:

Anyway ere's a pic of the silver cog.......geeze, some guys want to change the front, but the rear takes no time and only uses two sockets and the chain adjuster from the tool kit.... ;)
