I 100% agree with the 250 Ninja Spec class.. In fact, I am going to get one ready for next year. .. . but HEY, want cheap racing??? Don't forget about us little old guys.. This one was just built by me over my STAYcation holiday. Its a CB125s... Granted not big enough for the track, IMI for sure but you get my drift??? Ala, CB 160,350, - RD 350, 400 - GS And GT series... Vintage racing at is finest. Talk about Cheap!!!! My race weekend for this little guy including my RD is Gas and Entry Fees. Tires are less then 50 for the set... hahaha
