gee i guess i need to ditch my ancient conventional telescopic forks for superior USD forks on my 03-04 600RR......... but this is the same ancient outdated conventional telescopic forks i used to beat the competition running superior USD forks on their R1, 1000RR, 1098 superbikes during my last race.
i also need to ditch my ancient conventional Nissin brake calipers in favor of the superior Tokico, Brembo, Soqi monoblock radial calipers that the aforementioned bikes use............ but wait this is the same ancient conventional brake calipers i used to outbrake my competition.
don't underestimate what a resprung & revalved conventional fork can do, a well tuned conventional fork can perform just as well as a well tuned USD fork, running USD forks don't mean squat if you can't dial it in & for street riding you won't notice the difference between a conventional & USD fork.
same goes for the brakes, for street riding you can't tell the difference between conventional vs radial calipers unless you're braking at the limit.
it's a good thing i spent my money on Ohlins springs & Bitubo valving shims to tune my ancient conventional Showa cartridge fork, if i happened to join the USD conversion bandwagon i would have just ended up with a stock under damped & under sprung forks that would require new springs & new valving to make it work which would have cost a lot more.
besides i love to beat guys on modern, technically superior 600, 750, 1000, 1200 sportbikes with my ancient, outdated & inferior 03-04 600RR, if i lose to them i can just make up an excuse that it's my bike but if i beat them they have no excuse.
one of the guys i raced against told me to "upgrade" to a 1000, i asked him why? he said "so that we wouldn't be humiliated if we got beat by a rider on a 1000, to get beat by a 600 is just too much"
that is why i love my bike even more.
