Duke R:
Duke 690 R
For KTM, the range of single cylinder LC4s represent tradition, legend and future and well as performance, rideability and the smooth, quiet, harmonious running of the engine. When KTM introduced this motor concept in 2007, it elevated single cylinder enjoyment to a level that to date has not been surpassed. With the presentation of the Duke 690 in 2008 KTM caused another sensation among the worldwide community of Duke fans. But KTM wouldn’t be KTM when the ambitious developer wasn’t set on constant improvement and innovation. Now 70 full-blooded hp packed into a vehicle weight of just 148 kg lend the Duke 690 R unrivalled panache. Highest quality components and the unique optics are also typical KTM. As well as the highly potent motor, the 690R also features the orange frame specially reserved for the R models. Carbon mudguards, an extremely sophisticated fork and the new orange rear damper spring are among the outstanding features of the Duke R. Other improvements include an extended maintenance interval and ensure that this very hot street bike will continue to have no serious rivals.

The Duke R is the first 690 who is actually a 690 cubic engine. This is done with a giving it a longer stroke, Sorry if my english isnt good enough. It has 70 Hp from factory. Carbon front fender takes off 300g from the front wheel.

The 2004 525 SMC is not much like a SMR but a SX. SX frame, swing arm etc. I was told that of the showroom floor it was a 4 spd but that most were upgraded to 6 spd post sale.

here is mine with the 3.1 gallon tank and akrapovic exhaust.

In post #5 you say the 660 SMC comes with the BST40 carb, but it comes with an FCR41, same as the 625 SMC.

man.... I've got a TON of info to update to this. I really want to include a history of all the SMR models.... not to mention add the SuperDukes and the new 990 & SM-T.

Unfortunately, I can no longer edit the original content. Have been e-mailing Moderators to get back my editing wrights.

------ um.... Van Den Bosch? Post up a pic..... I'll then dig some more....

I've heard 70+ hp, light weight, kick start only, carbon fiber tank & fenders. Looks like the actual name is "KTM 660 Supermoto Factory Replica" and it is sofa king sweet!! :thumbup:

Some info in a post here:

Picture from SMR Magazine, says it was a 2002 model:

They are not replicas, they are actual KTM factory race bikes. You could order them through KTM dealers but they never came road legal, but it's easy to make them legal to ride on the road in Europe.

Here is a link to a thread on a UK KTM forum with lots of pics, these bikes have all the best parts, the whole subframe is carbon fibre. They weigh about 110kg and I have heard people claiming as much as 80bhp! But most people say they are around 70.

Here is my 04 625 SMC!! Got 42,000 miles. Love it!! Had a few problems.. Good thing I got extended warranty. It would have been really expensive if I had to pay out of pocket. Let see, main bearings went bad to due a defective crank. Both Intake and Exhaust rocker arm bearings failed and ruined cam. 4th idler gear came apart. Replaced all gears and shafts in transmission. With all the problems I had. I still love my SMC!! What blast to ride!!

BTW All LC4 engines have TWO oil pumps. One pump is used for the crank and piston. Second pump is used for transmission..

I have been following this with interest.

does anyone have the specifcations of the 2003 660cc motor, with no electric start. I got one that was slotted into a 2002 Duke frame for me. But all I know about the motor is that it was a 660 SMC from Europe. It has the oil resovoir behind the cylinder and does not run the oil hose to the holding tank on the frame.

bike now has a 660cc engine, slide carb and Sibring big bore pipes.




and can shred a cut slick on a "bad-day"



thanks
Tony
