"Iwaki (Koichi Iwaki) is a motorbike mechanic with big dreams of racing professionally. Then temptation arrives in the shapely form of Mayumi (Junko Matsudaira), the wild and free lover of Mitsuda (Yusuke Natsu), the leader of the Red Rose Gang, a pack of speed freaks tearing up the town. Iwaki meanwhile has his sights set on the sweet and innocent Michiko (Tomoko Ai), but any potential romance is hampered by her overprotective brother Tsugami (Sonny Chiba) and Mitsuda’s bullish plans to make Michiko his own trophy. Does Iwaki take the straight and narrow option, or opt for a more dangerous road?." - synopsis provided by the distributor

No information is provided about this transfer's source; that said, it looks like it comes from a dated existing master. Flesh tones look healthy, colors look good, image clarity is generally strong, there are times when the black levels are not as convincing as they should be, and there are no issues with compression.
Audio: 4/5
This release comes with one audio option, a LPCM mono mix in Japanese with removable English subtitles. The audio sounds clean, clear, and balanced, and range-wise things sound great.

Summary:
Teruo Ishii directed Detonation Violent Riders! His other notable films include Shogun’s Joys of Torture, Inferno of Torture, Orgies of Edo, Horrors of Malformed Men, The Blind Woman’s Curse, Bohachi Bushido: Code of the Forgotten Eight, and The Executioner.
A motorbike mechanic dreams of becoming a professional racer and finds himself falling for a girl linked to a motorcycle gang.
Detonation Violent Riders! is the first in a series, which will include three additional films. All four films feature Kôichi Iwaki, with the first three directed by Teruo Ishii. Detonation Violent Riders! is part of a subgenre known as Bōsōzoku, which focuses on a youth subculture in Japan that is associated with customized biker gangs.
Detonation Violent Riders! is a star vehicle for Kôichi Iwaki, whose real-life background as a professional bike racer adds realism to his performance since he performed all of his stunts. Although he had only appeared in a handful of films, he definitely holds his own alongside the rest of the cast. The cast’s most recognizable name is Shin’ichi ‘Sonny’ Chiba (The Street Fighter), who portrays Tsugami, a former professional racer whose character serves as a mentor to the protagonist. Another performance of note is Tomoko Ai (Terror of Mechagodzilla); she portrays Michiko, Tsugami’s sister and the protagonist’s love interest.
Though the narrative is barebones, mostly a means to showcase the motorcycle sequences, things move quickly, ensuring there is never a dull moment. Several characters exhibit psychopathic tendencies and show no regard for life. The film includes a significant amount of nudity, as well as a troubling rape sequence. Nevertheless, when it comes to exploitative and outrageous moments, Teruo Ishii had no rivals in 1970s Japanese cinema.
Carnage and chaos are center stage in Detonation Violent Riders!, and yet there are a few poignant moments that are effectively executed, notably a moment where a grieving mother is consoled by members of the gang her son was part of and a bittersweet finale, which serves as a perfect coda. Ultimately, Detonation Violent Riders! is a solid exploitation film that is a cross between Toei’s Yakuza and Sukeban films.
Detonation Violent Riders! gets a first-rate release from 88 Films that comes with a strong audio/video presentation and a trio of informative extras. Recommended.
