The Suzuki GT500 replaced the T500 twin in 1975. The new model looked very much like the classic T500, once sensationally fast and well-built machine, but in the mid-seventies already old-fashioned and smoky two-stroker. Its days were outnumbered. Suzuki made a good effort trying to modernize the once very popular model by releasing the GT500 that had a bigger tank, electronic ignition and a front disk brake. Confusingly, the T500 was renamed to GT500 already in 1971 in Japan.
