The Honda CBR450SR was a sports motorcycle part of the CBR series in Honda's range that had its debut in 1989 as a result of a survey with dealerships and the public in 1987 to find out what should be improved on the CB400 model.
The bike featured a fully faired bodywork with a modern design for that time and impress with its aesthetic beauty inspired by the Honda CBR250RR version manufactured in 1987, which shared many fairing parts.
Over the years, the CBR450SR didn't feature any mechanical, technical, or design changes, except for the 1991 and 1993 models that came with only graphics changes, such as the 1991 model that featured White, Red, and Blue colors and nicknamed Captain America and the 1983 model that was called Babaloo.
For suspension, the bike packed a 37 mm telescopic fork with 37 mm of wheel travel on the front and a monoshock absorber with 110 mm of wheel travel on the rear that provided optimum suspension performance.
As for braking purposes, the model featured two 275 mm discs with two-piston calipers on the front wheel and a single 220 mm disc with a single-piston caliper on the rear wheel that offered strong stopping power.
In the performance department, the 1992 Honda CBR450SR had its soul brought to life by a 447cc four-stroke four-cylinder liquid-cooled engine that delivered an output power of 47 hp at 8,500 rpm and 40 Nm (30 lb-ft) of torque at 7,000 rpm.
