Original: Track officials revised the 130R , redesigning it as a double-apex section , one with an 85 m radius , and then a second featuring a 340 m radius , leading to a much closer Casio Triangle ( chicane ) , with the chicane becoming a `` bus stop '' type for motorcycles .
Simplified: One apex had a 85 m radius , and the second had a 340 m radius . This lead to a much closer Casio Triangle ( chicane ) , with the chicane becoming a `` bus stop '' type for motorcycles .
