　KART’s particular part

---

　　KART has participated in the competitions 4 times, made 5 machines. We are particular about “aluminum space frame” consistently. It had been commented that it has low reliability from difficult weld and fatigue character, and cost. But we’re trying for design that can bring out aluminum all superiority,”　light weight”. And, there’s another special feature. That is “dry carbon”. KART has used carbon fairing from the 2nd machine. The beauty has become a synonym for KART. We aim for the top of podium with more evolved “The machine of KART”.

◆　YJ-R00(2004) Concept: run turn stop This is a legend of KART. We tide over “hellish one month” by great team work. Our first machine completed the race. Wheelbase: 1650mm Tread: 1200mm(F/R) Weight : 370kg (wet, include driver) Cento!
◆　YJ-R01(2005) Concept: AAA ~triple A for racing~ This machine is finished on 31st May 2005! However it has fatal error, then we made YJ-R02 from there. This is the shortest life. Whole running distance is less than 10km. Wheelbase: 1750mm Tread: 1250mm(F/R) Weight : 350kg (wet, include driver) Two pedals, colander intake
◆　YJ-R02(2005) Concept: AAA ~triple A for racing~ Frame concept is “the opposite to YJ-R01 anyway”.YJ-R02 manages to have parts layout miraculously, and it become compact and low center of gravity. This is our first racing car. Wheelbase: 1700mm Tread: 1230mm(R) 1160mm(F) Weight : 330kg (wet, include driver) Differential length and nonparallel double wish bone
◆　YJ-R03(2006) Concept: pursuit of functional beauty YJ-R03 is not the machine “for making”, but “for racing”. Troubles in each parts disturb good result, but its design leads to next evolve. Wheelbase: 1700mm Tread: 1200mm(F/R) Weight : 315kg (wet, include driver) Paddle shifter, handmade oil pan
◆　YJ-R05(2007) Concept: self create This is the 5th YJ series. Though frame has drastic review, this machine succeeds in straight-ahead evolution from former model. Light upright achieves drastic improvement of motion performance. Wheelbase: 1700mm Tread: 1200mm(F/R) Weight : 295kg (wet, include driver) Small differential gear, paddle shifter, improvement of handmade oilpan
◆　YJ-R06(2008) Concept: SMART This machine aims straight-ahead evolution. We reduce unnecessary things strictly, then YJ-R06 became the lightest machine in our history. Fairing is lacquer. Wheelbase: 1650mm Tread: 1200mm(F/R) Weight : 285kg (wet, include driver) Frame structure aiming at development of bending rigidity, steering system which has structural function, F/R upright have different making process, improvement of paddle shifter
