Club racing in the ‘70s and ‘80s was a melange of riders from all different financial backgrounds. You could race a (I did) FZ600 that was a low-rent effort, basically a stock bike (tuned by Kevin Cameron) with Wiseco pistons, Supertrapp pipe, Kehin flatslides, $40.00 ........... steering damper, $50.00 rear-sets, $25.00 fork brace, braided lines, aftermarket fork springs, $40.00 case guards . . . All of which ended up costing less than $4,000.00 - and it could be entered in F2, Middle-Weight Superbike and Battle of The Twins. And you would be racing against guys are full-out factory RS250s in F2, $30,000.00 Ducatis in BOTT, and under the radar Honda Hurricanes with insane amounts of cash invested in them (Daddy owned 3 Honda dealerships) in Middle-Weight Superbike. The guy who towed his 7 year old RZ350 with his ancient Subaru who lived on ...... burgers from the canteen and slept at night in the paddock in a pup tent, would be parked next to yuppie kid with a full Yoshimura GSXR750 who came with a mechanic and slept in a $70,000.00 RV and cooked sirloin steaks for lunch.
From what I’ve seen of club racing now, it’s pretty much all the latter, except the guy in the RV now eats vegan and gluten free.
