Why it matters
The revival of the inline-four engine configuration in the small-displacement category is a significant technical development for motorcycle enthusiasts.
Honda has confirmed production and delivery dates for two long-anticipated small-capacity motorcycles, the CB400 Super Four E-Clutch and the fully faired CBR400R Four E-Clutch, both of which will begin arriving at select Japanese dealerships later this summer, marking the revival of one of the company's most iconic naked-bike platforms.According to Honda Japan, the naked CB400 Super Four E-Clutch will reach select "Dream" dealerships first, on August 21, with the sportier CBR400R Four E-Clutch following roughly one month later, on September 18. Pricing for the two models has also been confirmed, with the CB400 Super Four E-Clutch set at 998,800 Japanese yen, or roughly 4,600, while the more expensive CBR400R Four E-Clutch will carry a price tag of 1,199,000 yen, approximately 5,500.
