Yes, you’re right on all that. We ran with the 400’s last year on some races and our lines in the corners couldn’t have been more different, leading to a couple of incidents. This year we also did a few races with them with a split grid, them 20 seconds in front, a few back markers were lapped but it worked well and everyone seemed happy. It’s always a balancing act getting as much evenness between bikes while also letting as many in as possible and the 400 class would probably want to retain as many bikes as they can. Now a 600 in a 400 chassis special has made fools of some of us this year, but that is another story.

I doubt it as it came out in 1995 a quick search gives this
I will try to find out for you
The CBR600F3 was the third generation of the CBR600F series. It replaced the F2, and was produced from 1995 to 1998. It had a modified engine, ram-air intake and cartridge forks. The 1997 and 1998 models also came with a deeper oil pan, sleeker tail fairings, seat and tail light, and a revised engine head netting about a 5 hp gain over 95/96 models. The CDI and ram-air system were also revised to allowed for smoother throttle curve over the 95/96 models, which could sometimes be jerky. The last made 1998 models came with another revised engine head which resulted in a slight power gain. In 1999, it was replaced by the CBR600 F4.

In 1996 and 1998 the CBR600F3 was also sold in "Smokin' Joe's Replica" versions in the USA, Canada and Australia (1998 only).

Cycle World tested the F3's acceleration from 0 to 60 miles per hour (0 to 97 km/h) at 3 seconds and 0 to 1⁄4 mile (0.00 to 0.40 km) at 10.9 seconds at 125.28 mph (201.62 km/h).[5] Motorcycle Consumer News recorded a 0 to 60 mph time of 3.7 seconds and a ​1⁄4 mile time of 11.03 seconds at 124.06 mph (199.66 km/h)[6]

Thanks, as the frame is unchanged from the 92 model and the engine changes fall within modifications allowed in the rules as do brakes etc. it does fall within the rules.
We've had F3 racing with us from the start and they've fitted in well. Nice to tune and reliable as, so don't break the bank.
