"A Japanese Twin with a Big Bike Punch" | |||||

It looks like a 250; it feels like a 250. The difference is apparent only after a few miles in the saddle of this 305-cc sportster. A mere 58 cc separates the two models. Yet, this very difference adds up to a worthwhile bonus in punch and acceleration. The 305, at 96 mph is fast - and decidedly quick off the mark, with a stinging quarter-mile in 16/s. This is over a second better than the 247 cc twin. |

However much the 250 impresses, its bigger brother cannot fail to be that much better. It is everything one expects from Honda, together with a helping of big-bike punch that comes as a pleasant surprise. Closely allied with performance are revs - all 9000 of them. The CB77 thrives on [high RPM] and isn't happy until 5000 have accumulated on the neat revmeter dial. |

RPM Range Like all Hondas, the test model was happiest at intermediate speeds if frequent use was made of the gearbox. The main object is to keep the engine turning over above 5000 rpm. Below this the engine is definitely out if its element. The CB77 revs so easily and so reliably that the high engine speeds are no disadvantage. That is what the OHC engine is built for, and what it likes best. Gear change on the test model was lighter and more pleasant than is usual with the big Honda twins. Only a slight clunk was noticed when engaging bottom gear from the rest. |

Top Speed & Gearing One poor feature was a slight roughness in the transmission as the clutch was engaged. However, previous experience has shown that this is peculiar to the particular model on the test. The machine is slightly overgeared in top. 9000 rpm represents 103 mph, but patient repetition of electronically timed runs proved 96 mph to be absolute top whack under normal conditions. Nevertheless, 96 is not too much effort for the CB77 and there is a margin for the day when you are going downhill or there is a force 8 gale behind you. Then it is highly likely that you will pass the magic 100 mark. |

Although some 4-mph fast at 30 mph, the speedometer became progressively [more accurate] until at 80 mph, it was almost spot-on. After 90 mph, perhaps because of high-frequency vibration, the instrument was optimistic to the tune of 10 mph.
For such good performance you expect good brakes. And you certainly get them on the 305.Very smooth and progressive, with no tendency for premature wheel locking. That's a description of the potent twin leading-shoe stoppers. They were much more efficient at high speed than the 34 feet braking figure from 30 mph would indicate. |

No topping-up of the oil sump was necessary throughout the 1000-mile test, and the power unit remained markedly clean.
With fully adjustable controls the Honda, is soon tailored to fit any rider. It is extremely comfortable and is superb for tucking in and getting down to it.
For night riding the main beam intensity was adequate for 50 or 60-mph cruising. A good feature is the clear top cut-off to the dipped beam. |

Steering & Suspension Handling needs only slight improvement to make it perfect. There is undoubtedly still a trace of underdamping in the suspension. It would be passed off as unimportant on a lesser machine, but with the potential of the CB77 the tendency to wallow on bumpy corners can be rather disconcerting. Steering, however, is light and positive and the bike holds the road well. |

Whichever way you look at the Honda, whether you like a high revver or not, there is one thing on which everyone must agree; the detail finish is excellent. From the twin-leading shoe brakes to the revmeter and speedo unit, everything is just so. For your 280 pounds you get an economical, high performance sportster plus a liberal help of the sort of quality you would expect only on a much more expensive machine. |
