I shift between 7 and 8k, and at 6th gear I top off at 10k rpm and max speed 96mph on the track straight away, down shifts I try to stay in the 6 to 8k range!

Too late a shift, and I will lose engine power after 8500rpm. Engine will cut completely if I gas it too much in 4th or 5th gear when it should be in 6th. Not fun on a track when that happens.

Just got the CB300F and took it easy the first couple of rides to get a feel. Third ride I spun it up into the 6-8k range and found it much livelier and fun. Nice change from the KLR650.
Was concerned about buzzy at higher RPM but Grip Buddies took care of any that was there. Very pleased so far.

I usually run it up a bit higher than 5k. You can really feel the engine get on the pipe at about 6.5k. So I run it up from that. I’m mostly city with some twisties thrown in a couple of days a week. The engine is made to rev up so I do. 😀

Old enough to remember 2 strokes eh ??
I'd always lusted for a CB400F four with Vtech which had a dramaticalyy similar effect but out of my price range. Really after 57 years and a few fast bikes ,,,,notably the CBF1000 recently ....the CB300F is just fine with insane gas mileage and enough power to keep up in the severely restricted speed limits in Australia.

I shift when it feels right but usually 7k rpm+ unless in a hurry, The single 300 thumper does "okay" at lower rpms tho, Not real bogging unless you try and pull in a higher gear at low rpms. It is decently polite in reminding me.
A rev limiter at 10,500 on the CB300F I have not hit yet I don't think .....hopefully less abrupt than the NC700 which was THE worst demo ride evah. :eek: 6500 hard rev limiter made for a horrid ride experience....yes it pulled....then it stopped just when most bikes are getting into the sweet spot.

I wind it up a bit more in traffic off the line and upshift 5500 to 6000 rpm. However, when I downshift coming up to that next stoplight, I get a loud disquieting thunk going down the gears ad the engine is still spinning pretty good. I'm not very mechanically minded, but it seems I may be causing some damage, am I?

No damage. That clunking is normal. If the rear end doesn't feel like it's locking-up and sliding the rear wheel, you're matching engine speed and down-shifts properly enough. As the bike gets more miles on it, and, as you get more familiar with your shift points and engine speed, it will shift easier and smoother. I'm not throwing stones here.... every bike is different... no matter how experienced a rider you are.. they're all different.. So, all's good.

I usually don’t get a “clunk” until shifting into first
