KTM decoder: bare numbers and the bikes behind them

KTM filter values start with engine size, so a lone 690 can be a Duke, an Enduro or a Supermoto. Each row pairs filter values with the bikes behind them, read from the listing titles, which also carry the years.

Slip-on, full system, Race: how the KTM kits split

Slip-on kits take the place of your silencer (muffler), link pipe supplied. Full System kits turn up mostly on the dirt bikes. Double bolt-on kits belong to the 950 and 990 family. Race listings sit beside the standard ones for the Dukes, RCs, Adventures and dirt bikes, and most carry a No on the removable DB killer (baffle) line. A Decat Pipe carries no catalyst.

On a 250 to 450 F dirt bike, decide between a full system and a slip-on before comparing lines, since the listings offer both side by side.

KTM questions we hear most

Why do KTM filter values look like bare numbers?

KTM names bikes by engine size, and the model filter keeps only that number for many Dukes and Adventures. The decoder above ties each number to its bikes, and the listing title then confirms the year.

What do Race listings look like on a KTM?

They sit beside the standard slip-on for the 125, 250 and 390 Duke, the RCs, the 790s and 890s, the Adventures and many dirt bikes. In most of them the removable DB killer row reads No.

Which KTM street bikes get a full system?

The 690 Supermoto, 690R SMC, 690 Enduro R, 950 and 990 Adventure S, 1290 Super Adventure R / S and 1390 Super Adventure R/S, plus the RC8R.

How far back do the KTM listings go?

The oldest are the 640 Adventure / LC4 and the 520 EXC, both from 1999. The Duke II appears in 2000.

Which KTM models have a Decat Pipe?

The 125, 250, 390 and 690 Duke, the 790 Duke and Adventure, the 890 R Duke, 890 L Duke, 890 SMT and 890 Adventures, the 1050, 1090 and 1190 Adventures, the 1290 Super Adventure and Super Duke R, and the RC 125 and RC 390. It lists No for the removable DB killer.

Is there a KTM kit with a spark arrestor?

One 350 XC-F listing, a Pentacross Inox full system, names a spark arrestor in its title.
