Hi, to do the conversion you need, obviously, a KTM 1290 17 SD, or SD GT, front rim, SD 1290 rotors, original SAS rotors are 6 bolts rotors and rim is 5 bolts, front fender (you can use original but it's quite big for the new tyre) from a 1290 SD or KTM 990 SMT.

Once you have this parts, you need two 5mm rotor spacers, two 2 mm axe spacers and a new ABS tone ring with different number of spaces cause you can change tyre diameter in your ECU

A friend of mine is a engineer who have access to machinist so I decide to ask him to help me and we made a complete kit, if you are interested please, send me a DM

Quick question for clarification. Do you also have to adjust something in the ECU/software? (Above you state ‘cause you can change tyre diameter in your ECU’) or did you mean to say ‘can’t change…’

I changed the rings on my SD to get a more accurate Speedo, but didn’t change anything in the software. It was a 2015 though so just checking.
Cheers!

Just did a 17” front wheel conversion on my 2022 SAS. Had Woody’s Wheel Works build a wheel for me. Just had to swap over the original rotors, tpms and and abs rings. No machining required. So far so good. Think I’m going to get a matching rear wheel but in 17x5.5 instead of the stock 17x5 size. This would allow me to run a wider 190/55 tire comfortably.

Due to weather and having other bikes to ride, haven’t been on my 1290S since the 17” front conversion. Just wondering if anybody with the conversion has been on a track day yet?
wondering where I should have my front forks at for protrusion through the top triple?
before I did the conversion I had it sticking through 25mm more than factory.

I adjusted the forks so that they top of them were about flush with the top of the triple clamp. So lowered them by approx 25mm. About as low as they could go while still making good contact with the clamping surface. Doesn't fully compensate for the change in trail induced by the 17" conversion. But it figured it was a good starting point. Bike steers/handles very well with preload set to 70-80% (I weight 195lbs without gear).

I also have a Super Duke RR (converted from an R) but with CF wheels and other upgrades. That bike is a true scalpel and one that requires full attention at all times. The SAS with the 17" front wheel conversion is something else completely. Super comfortable, alarmingly nimble for something that large and very easy to ride fast over any kind of road surface. Truly amazing and a lot more fun to ride than the Ducati Muti v4 Pikes Peak I currently have parked next to it.

You answered my question before I could ask it. I haven't ridden a V4 PIkes Peak, but I did rent a V4S in Italy and was not happy with it. I greatly prefer the handling of my old 1200. A 1290 S with 17" front and 5.5" rear might be the ticket.:unsure:

Hi I’m interested in buying this kit,how much are you charging and can you post it to me ,I’m in Sydney Australia Thanks Stuart

I have a 2020 SAS Converted 17” front. Used the SDR GT front wheel with 5 mm spacers and new tone ring. I did not move the front forks down , I left them where they were stock. Do it taking the front down approximately 1”. So 25.4 mm. This of course will put more weight on the front tire and it will decrease trail on front wheel.

Decreasing the trail does make the steering much lighter. But I have had it to 125 mph no wobble and for me at least I preferred the quick steering. I did put a HyperPro RSC steering damper on it. But for me zi would not push forks down. I like the steering.

As far as the rear wheel I put a 180/55 R17 Rear on it. I would not go any larger on the 5” rim. Personally I don’t think the 5.5” rim and a 190 will make any difference. As far as performance and tire wear after almost 5,000 miles on a Metzler Sportec M9 RR’s Most of my riding is taking it out on some local twisties so the wear is completely even an the tire has not flat spots.

With the new SDR gt making as much power as the gen 1 SDR and the new suspension the sas is fitted with I have to admit I'm curious? My sas gets heavy gravel and trail use and i'll probably use it for days over 400 miles for comfort. Have any of you guys considered the gt instead of modding the sas if you're not going offroad?

Ergonomics is the key for me. Ride position is much more comfortable in a SAS than in a SDR under my personal opinion.
