Just got the Michelin's and HOWLEE SHIIIYETTE they are so much better. Have to run them in but the bike just felt better to handle. Maybe that was the service as well @ 5000Ks. The guy did point out that my chain is in bad shape and will need replacing at 10,000 Kms. is that normal? maybe for stock chains or something?

I am thinking your not getting lube on it often enough or adjusting the wheel back as required. You should be 30th plus from chain on such a light low output bike.

I don't know what the stock tyres are, or what (specifically) you replaced them with. But it's pretty likely the majority of what you're feeling is the difference between knackered tyres and brand new ones.

And 10,000km seems very low for a chain on that bike.

Not always. Honda put a crappy chain on the NC700 from factory which had a short life. Boss had his factory chain replaced under warranty from memory.

OP, did you maintain the chain?

Re tyres, you're not actually stating mileage but comparing old worn tyres to new tyres never works and this is because the worn tyre has a bad profile.

I think cbr300r's like the cbr250r before it run IRC road winners ex factory. They get bagged a lot for being budget tyres but tbh I found them great in all weathers whether on road or track. The fork springs and rear shock on these bikes are set up for 75kg riders (built in Thailand) so good gains in handling can be had by adjusting SAG (replacing front springs for your weight - check racetech's site for spring rates [or adjusting the preload by changing the length of both fork tube spacers] and adjusting the rear shock a click or two). It's not uncommon to have SAG of 60mm with a 95kg rider on so, yeah the springs are on the soft side for heavier folks. Adding a bit of preload to get SAG between 32-35mm makes a night & day difference, in a good way. The chain should last longer than that using stock sprockets, less if the front cog's been swopped. Check the chain tension regularly to avoid excessive wear. Maybe add 10mm in chain slack to Honda's spec and you'll be right.
