It has been 5 months since I purchased a 1995 Honda CB400 Super Four motorcycle to ride in Moscow. The main purpose of this bike was a commuter to get me to and from work, and for small outings and rides on the weekend.
As far as modifications go, the bike has:
This bike makes a great commuter. Fuel economy is around 6L/100km, or 8L/100km if you push it. The torque curve on the bike is very linear, giving you confidence across the entire gear range. While the bike seating position is low, it is still quite comfortable for me (190cm in height). Flicking it in traffic is fairly easy, the bike weighs a mere 180kg, making it perfect for lane splitting and low-speed maneuvers. The dual front disc brakes also inspire confidence in braking ability. The 400cc powerplant is mated to a 6-speed transmission, making it the perfect starter bike – it has all the perks of its “bigger brothers” without the additional weight and unexpected torque.
The 1995 CB400 Super Four motor has an extremely linear torque curve. Even after 35 000km on the motor, it still easily starts and is as smooth as ever. The only issue with this motor is that it’s carbureted, and the carbs do need to be synchronized and cleaned before the start of the season. Since it’s an older bike and the carbs are worn, it does have some issues with running rich. This can be fixed by installing new rubber seals. The 14000rpm redline is impressive, and the motor is an inline-4. With a proper exhaust, it doesn’t sound any worse than it’s liter capacity bigger brothers.
The transmission on this bike is nothing short of epic. Even compared to my ’07 Kawasaki ER-6n, the transmission shifts much smoother no matter if upshifting or slowing down. The original clutch is not slipping in the very least. Almost every owner of this bike can comment on how nice and smooth the tranny is.
It’s an entry level bike, so there isn’t much to expect in terms of suspension quality. I honestly find it a bit too soft for what it is. The rear has a twin-shock suspension that has adjustable preload/spring tension. Front is dual fork non-adjustable, however the firmness can be adjusted by adding another 50-100mL of oil over specification. For what it is, it’s fairly decent.
Overall, I would highly recommend the Honda CB400 Super Four to anyone thinking of buying a first bike. It has enough power to keep up with bigger bikes, is still faster than 95% of cars on the road, and yet easily forgives mistakes thanks to its low weight and center of gravity.
