You don’t have to find it the most beautiful, and it isn’t the lightest anyway. But the most robust of all: CB 250 G from 1974.

The electric starter lies in front of the feet of the light metal cylinders, and the kick starter towers above the gearbox on the right. Practically just. And good, like the whole Honda CB 250.

A really good loiter

Anyone who wanted to be ahead of the popular quarter liter in the early 1970s owned a Suzuki, Kawasaki or Yamaha. On the other hand, those who wanted more permanent, yet brisk locomotion resisted the trend towards the top two-stroke engine and simply bought a Honda CB 250 K.

Wild times, also for manufacturers: Honda had just been hailed because it was wrestling four-stroke liter output of over 100 hp and combining this with good everyday practicality, when Suzuki went into the fast lane in the important quarter-liter class in 1966. The T 20 allegedly had 29 hp, and things got really serious when the adversary – from an enlarged dealer network in the meantime – sold the 30 hp T 250 from 1969. At the beginning of the 70s, Yamaha and Kawasaki also pulled out sharp two-stroke blades, and no speed orgies were of any help against this overwhelming power. It felt like the Honda said goodbye C.B 250 K in the touring segment.

Honda CB 250 K can stroll really well

Its pragmatically designed counter-rotating twin also differs from that of its predecessor, the CB 72. It now has a primary drive with gears instead of a chain, five instead of four gears and can be ventilated by constant pressure instead of simple slide valve carburetors. 26 hp at 10,150 rpm were on the German data sheet for the K0 model, and from 1970 for the K1 even 30 at 10,500. However, improvements to the camshaft, oil pump and timing chain tensioner reveal that even a Honda can be born with defects. Above all, the camshaft problems were still not completely resolved, even with the K4 from 1972, which adorns itself with a disc brake as standard and moved into the 27 hp class from the following year. Proper handling and proper stability characterize the driving operation, sensible accessory struts make the Honda CB 250 K faster.

The engine is really fixed if you never let its speed drop below 7500 rpm. And if you don’t shy away from the red zone, you can try to crash around the Nurburgring even faster than Ernst “Klacks” Leverkus: The MOTORRAD tester set his fastest 250cc lap on the Honda in 1972. Go then. But the best thing is that the Honda CB 250 K can stroll really well and pulls in good gear even under 3000 tours. Incidentally, with the successor, the CB 250 G, Honda demonstrated great strength and eliminated all known errors. A trochoid pump instead of a piston pump ensures a powerful throughput of lubricant, also on the camshaft now rotating in three bearings instead of two. Changed valve timing broaden the range of services that can be used, and a six-speed gearbox provides even more leeway. The best CB 250. Unfortunately, the heaviest too.

The CB 250 models of the K0 to K4 series are the epitome of the boom time and at the same time represent a highly successful Honda era. Many apprentices and students dreamed of the CB 750, but drove the low-insurance Honda CB 250 K. Accordingly, it is one of the most common youngtimers today with correspondingly moderate prices. Even good copies go away from 1800 euros, the 250 G is occasionally even less. However, the K engines often require a cylinder head overhaul. The spare parts situation is quite relaxed.
