I don't mind them. Even after they wore out, I replaced them with stock. They last forever. For street riding I think they are OK. I also rode on Ortega highway (twisty) and honestly went faster on both my old CBR250R and the 300 than my old GSXR. I do have problems in the wet or when it is extremely cold out. They get slippy. I take it easy. If tires weren't so expensive and I could put them on myself, I would get other sticky rubber, but for a majority of street and back road riding, the IRCs are great. Probably not a popular opinion
Iv pushed them hard on 38°c day going home from work they work really good when really hot but iv had same problem in the cold they slip around a bit i really want to get diablo rossa 2 tyres but funds havent been there since moving house iv had them kick out sideways under heavy braking but abs took control thank god lol
Like the rim tape, nice and subtle.
Ive done 12k on the Road winners, on my 250R & now the 300. A mix of touring, sports riding and track days.
I think they are actually really good value for money and perform pretty decently for a stock tire. Once warm you can push them with confidence and I've had them 'ball up' on the sides at a track day when pushed hard with out letting go.
Obviously they are designed to give reasonable milage so they're never gonna be a super sticky soft compound tire, hence the tendency when cold/wet to slip a little.
Having said all of that I do have a set of Michelin PSR's in the cupboard waiting to be fitted once the IRC's are stuffed! I'm curious to try out a radial tire on the 300. But if I was strapped for cash I would buy another set of IRC's.
Thanks man i just found out today my stock tyres are not the average rx 01 they are the rx 01 spec r i read on irc website that they are designed for more aggressive rideing so out of curiosity i road my my mates 250r with rx 01 on it my tyres can be pushed alot harder
