Very vague on details as always. All he hints at is a bigger engine in the Himalayan - that could just be boring it out to 500cc.
The Himalayan has been promoted in the UK all this year, but there's still no sign of it in the dealers, and it's not even mentioned on the UK RE website.
Maybe this is why it's been delayed:
https://www.rushlane.com/royal-enfield-himalayan-quality-reliability-12237993.html"It has been over a year since the Himalayan has been launched. Problems faced by owners range from gearbox failure to paint chipping and blocked fuel pipe. Owners also have to deal with the bike pulling to one side, disassembly of front fork and rusting of components."
"The list of customer complaints include rusting, stalling, electrical failure, fogging of instrument cluster and rear tyre locking. Even as Royal Enfield tries its best to rectify all these issues, the steady flow of complaints makes it difficult to keep track while the bike itself has lost its credibility standing in the market."
