Moriwaki Engineering is a Japanese manufacturer of speciality high performance products andmotorcycle accessories.

Mamoru Moriwaki is a Japanesemotorcycle tuner, race team owner and founder of Moriwaki Engineering, a Japanese specialty engineering company that designs, manufactures and sells high performance parts formotorcycles andcars.^[1]

His motorcycle industry career is closely intertwined with that ofPops Yoshimura, another respected motorcycle tuner.^[2]

Moriwaki began his career as amotorcycle racer forHideo "Pops" Yoshimura, a respected motorcycle mechanic and tuner involved in Japanese motorcycle racing.^[2][3] Moriwaki received no formal training in engineering while working for Yoshimura. Instead, he became self-taught, learning about mechanical engineering from books borrowed from his local high school.^[2] Moriwaki married Namiko Yoshimura, Pops’ eldest daughter, while he was working for the company.^[2][3] While working for the Yoshimura racing team, Moriwaki also successfully competed inauto racing, driving a Yoshimura-preparedHonda S800 sports car to a class victory at the6 Hours of Fuji endurance race on July 26, 1970, and the GTS1 Class at the 1971 Japan Grand Prix.^[4]

In 1971, Yoshimura made the decision to move his company to the United States to take advantage of the burgeoning American motorcycle market.^[5] Moriwaki did not agree with Yoshimura and refused to leave his home in Japan.^[2] This created a rift between the two men; however, within a year Yoshimura had returned to Japan and sought Moriwaki for help after he had been cheated out of all his money in a business transaction in America.^[2] Moriwaki loaned Yoshimura money to re-establish himself.^[2] Yoshimura would go on to establish one of the premier manufacturers of motorcycle high performance parts in the United States and became closely associated with theSuzuki racing program.^[5]

Moriwaki remained in Japan and in 1973 he founded Moriwaki Engineering inSuzuka City, Japan. He became known for modifying engines and constructingframes for theKawasaki Z1.^[2] His bikes were successfully raced in the AustralianSuperbike championships in the late 1970s by New ZealanderGraeme Crosby.^[6] Crosby and co-rider Tony Hatton finished in third place at the prestigiousSuzuka 8 Hours endurance race in 1978.^[7][8] Moriwaki's reputation continued to be enhanced when Crosby and Akitaka Tomie qualified a Moriwaki Kawasaki onpole position at the 1979 Suzuka 8 Hours, ahead of all the major factory racing teams.^[9] At the 1980 Suzuka 8 Hours race, the Moriwaki team ofDave Aldana and David Emde qualified in a respectable second place ahead of the official Kawasakifactory-backed team ofEddie Lawson andGregg Hansford.^[10]

After Crosby went on to race in theworld championships, Moriwaki hired Australian riderWayne Gardner in 1981.^[2] Also in 1981, Moriwaki developed the world's first aluminum frame for large capacity motorcycles and entered them in competitions.^[1] Gardner and John Pace qualified their Moriwaki Kawasaki on pole position at the 1981 Suzuka 8 Hours, once again beating all the major factory racing teams.^[11][12] Gardner then rode the Moriwaki Kawasaki to an impressive fourth-place finish at the 1981 Daytona Superbike race behind Yoshimura Suzuki riders Crosby,Wes Cooley and Honda'sFreddie Spencer.^[13] Moriwaki and Gardner proceeded to compete in the British championship, winning their first race in England.^[6] Gardner entered the final race of the season with a chance to win the title but, an engine misfire relegated him to third place overall in the championship.^[6] Gardner's impressive results on the Moriwaki Kawasaki eventually earned him a contract with theHonda factory racing team and an eventualworld championship in1987.^[2][6]

In the 1980s, Moriwaki became closely associated withHonda Racing Corporation, the racing division for the Honda parent company.^[2] Moriwaki was the first outside firm allowed to use one of Honda's racing engines.^[2] From2003 to2005, Moriwaki competed in the premierMotoGP class with aHonda RC211V engine in a Moriwaki designed frame.^[3][14] The firm gained valuable knowledge from this experience and in2010, a Moriwaki-framed machine run byGresini Racing took the inauguralMoto2 title with riderToni Elias.^[2][15][16] On theMD600, Elias won 7 races with the bike and secured the championship with a fourth place at theMalaysian Grand Prix, held atSepang.^[17]

The Moto2 formula is based on a universal engine and engine-ancillary equipment specification, with identical controlled engines supplied to teams via the organisers, previously based on theHonda CBR600RR superseded by theTriumph Street Triple RS 765 from the 2019 season.^[18] Fuel, oil brakes and tyres are also controlled. Teams are able to use any supplier of chassis, suspension and bodywork under strict regulations to enable no one team to dominate by technology or expenditure.^[19]

In late 2018 atEICMA, it was announced that Moriwaki would join withHonda Racing Corporation to run theHonda Fireblade inWorld Superbikes during 2019 with ridersLeon Camier andRyuichi Kiyonari. Initially using Japanese Superbike race series specification as a base-setting, the team collaborated with Europe-basedAlthea Racing.^[20][21][22] Previously Honda's alliance was withTen Kate Racing,^[23] but due to poor results Honda decided on full-factory backing with long-term partner in Japan motorsport Moriwaki Racing.^[24][21] Previously Midori Moriwaki was Team Manager for KYB Moriwaki Motul Racing inEndurance events.^[25]
