KTM looks set to replace the 390 single with a new 490 twin-cylinder
KTM’s long-serving 390 single could be heading for retirement, with a new sub-500cc parallel twin waiting in the wings.
KTM looks set to retire one of its longest-serving engines, as the days of the 390 single-cylinder appear to be numbered. For more than a decade, the 390 has been the backbone of KTM’s lightweight A2 range, underpinning global sales with bikes like the Duke, RC390, 390 Adventure, Enduro R and 390 SMC R.
First launched in 2013 as a 373cc single, the engine grew to 399cc in LC4c form for 2024 and now powers the latest-generation 390 Duke and Adventure. But with limited scope for further development under tightening regulations, reports from India suggest KTM is preparing to move on, and it’s once again leaning on long-term partner Bajaj to make it happen.
The replacement is expected to be a parallel twin, likely sitting in the sub-500cc class. While there are no confirmed technical details, output would almost certainly target the A2 ceiling, meaning somewhere around, or slightly above, the 45bhp produced by the current LC4c motor, which itself sits just shy of the 47bhp A2 limit.
Such a shift would align KTM with much of the current A2 market, where twin-cylinder engines are increasingly the norm. Rivals already operating in this space include Honda with its CB500 Hornet, CBR500R and NX500, BMW with the F450 GS, and Kawasaki, which previously fielded the KLE500 in the same capacity bracket.
As for timing, don’t expect anything imminent. Early concept models could appear at the 2027 edition of EICMA, although production-ready bikes are more likely to surface in 2028.
