Indeed, Suzuki are notorious now for having short service intervals, while Nissan have followed the sensible trend of reducing the necessity.
One Nissan exception though. The Leaf electric car. First service at six months, then at first twelve months, then annually regardless of how low the mileage. It's the battery checks they fret about.

Their bikes are just as bad..... I have a Suzuki and a Yamaha.
Service interval is every 3,500 miles on the Suzi but 6,000 miles on the Yam.
Valve clearance check/adjustment is 7,500 miles on the Suzi, but 24,000 on the Yam.
Although to be fair, the Suzi is old school screw & locknut valves and the Yam is modern bucket & shim. Even so, every 7,500 miles for valve clearance check is ridiculous and i do em every 15,000 unless they sound really rattley.
