CB650SC. Hydraulic lifters, electric start, shaft, twin front discs. Fast enough but No "surprises". 4 blasted carbs to keep synced , but, out there, not hidden under nacelles or farings. More reliable than a Ninja, so more time Riding than in shop. Hondas always run, just make sure clean, fresh gas. U Will-drop her at least Once, plenty of old Hondas Fours out there .( A Harley crash bar fits, with slight mods.) Worse to drop a New 250 Ninja or YZF-R3.
Edit: A Night Hawk Is a street sports. So described in old Honda catalogs. And, by insurance agencies. Not as "fast" as a 650 Ninja or FZR 1000, No, but gets Out of her own way and gets Out of tight situations, well. A bit faster than a 1440 cc Harley-Davidson, handles better when lowered an inch. Some years had dual front discs that make a lot of difference, too. This "standard" business I've never Heard of in 22 years riding/35 years having licences. Until yesterday, on Wiki..which is often very inaccurate. Anyone can edit Wiki, so not admissible in court., often black lies in it, too.
