Check the 1/4 mile thread. A board member has their 6RR up to 10.3s 1/4 mile times already, not broken in. Doh, that's sriously smoking, about what a good 1/4 miler will do on a stock/street R1 or 954.
The J series ZX6R will see high 10s, low 11s at about 125mph for a good rider. Ryan Schnitz and others got their J series (2000-2002) bikes to high 9s. Doh.
The 600s need practice and lowering to do well. I'm happy (for now) with my low 11s. My other 600 buds usually see high/mid 11s (launching is a biatch).
