Im planning on buying a ktm duke 390, and im pretty sure im going to change the rear sprocket for a bigger one as i want to be able to pop wheelies without too much clutch and get better accelaration. However i expect a 56T will be too much of a compromise to speed. Have anyone tried these 2 sprockets? How did it feel? How was the wheelies? what was the highest comfortable speed for the bike?

Additional question, is DNA stage 2 filters and powertronic worth it? Is it noticable changes in power and general riding?

thanks in advance

Hiya. Goto a website called gearing commander and enter your buke details. You can find out speed in each gear, chain length needed etc for any combo you want to check. 48t would help but is not big enough for most stunters imo

Gearing commander and similar are great but on a small capacity bike you don’t always get the results you might expect in terms of speed because the site assumes unlimited torque.
