My 2019 manual is the same. In 40 years of riding ive never had to replace the throttle or clutch cables. Brakes, oil, wheels, and tyres are on my first list whilst servicing. followed by the bolts and a grease up and also a good look over the bike. I only replace if the parts have worn out or have deteriorated in any way. I think you may have to remember that the manual is a translated Indian book where the road conditions and temperatures that we do not get in Europe.
