4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Succeeding the 2014–2023 1290 Super Duke R (1,301cc, 180 hp), the 2024+ 1390 Super Duke R bored the LC8 V-Twin out to 110 mm (1,350cc), adding intake Cam Shift variable valve timing, tank winglets, a 17.5 L tank, and 190 hp / 145 N·m.
Oil & Clutch Mechanical Engineering Note
Because pressurized engine oil actuates the 1390’s intake Cam Shift variable-valve pins alongside feeding massive 110 mm pistons, clean full-synthetic SAE 10W-50 JASO MA2 oil (3.6 L with the 61338015200 element and dual cleaned screens) is vital.
Garage Wrenching Gotchas
- Watch the staggered twin-spark specification: each cylinder takes ONE inner plug (NGK LKAR9DI-10) and ONE outer plug (NGK LMAR7DI-10) with different thread diameters and heat ranges—never mix them up!
- The single-sided swingarm rear wheel nut requires a massive 60mm socket torqued to 250 N·m plus its safety retaining clip—never attempt rear tire removal with improvised adjustable wrenches.
5. Frequently Asked Questions (FAQ)
Why is the KTM 1390 Super Duke R actually 1,350cc?
1390 is KTM’s generational badge; mechanically, boring the 71 mm-stroke LC8 V-Twin from 108 mm to 110 mm raises true swept displacement from 1,301cc to 1,350cc.
How much oil does the 1390 Super Duke R take and how is the level checked?
Service fill with filter (61338015200) is ~3.6 L (3.80 US qt) of SAE 10W-50 JASO MA2 oil. Because it is a semi-dry-sump LC8, always verify the sight glass 1 minute after shutting down a fully warm engine.
What is the difference between the 1390 Super Duke R and R EVO?
The standard R uses manually adjustable WP APEX suspension, whereas the R EVO adds 3rd-generation WP APEX Semi-Active electronic damping and auto-leveling preload; all engine and fluid specs are identical.
