Just what the title says, curious what everyone thinks.

IMHO the 18 model doesn't need any "must have" mods unless you ride at a top level pro. As a vet int. mx rider the bike is very good off the showroom floor. The only thing I can think of would be springs if you're not within the weight range of the oem springs.

I’ve already done springs/valves, I’m thinking about a hammerhead offset shifter, being that my feet are size 13 I sometimes have a hard time getting under the shifter. Has anyone cut the backfire screen out? If so, was it worth it/easy to do?

I'm a size 12 feet & the stock oem shifter works fine for me. I remember seeing a couple of dyno runs done back in 05-08 on CRF450's with & without the fire screens. There was no noticeable gains to be had on the graphs.

Even though many claimed to feel a difference on seat of the paints. I'd attribute that to possibly a placebo effect.

I wear a 14 and yes couldn't shift my buddies 18 crf450. Overall great bike and shouldn't of rode it. I didn't want to get back on my bike after riding his.

My only complaint on mine is the clutch pull was a monster! Crazy stiff...

First things I did with mine were works connection radiator braces and Tokyo mods engine vent kit.
And disconnected the clutch switch for the electric start.

What’s the vent kit all about? I forgot to mention I’ve already done WC radiator braces, twin air radiator sleeves as well.

And the front tire that came on it is junk (MX3S) , I have so many knobbies ripped off before 10 hrs.

Vents the overflow engine oil out onto the ground (like the Yamaha) instead of into the air box .

I just put a Works Connection Pro Perch on mine and the pull is much better. Well worth the cost, IMO.

I ended up putting the magura hydraulic on mine. It's still stiffer than my other bikes but much much better.

Replace brake fluid with high temp good stuff. TM design works slider and chain guard.

Remapping made for smoother off idle throttle response and revved out better.

Revalve by Enzo fixed issues I had with stock settings.

48 tooth rear sprocket fixed gear spacing issues I had on tracks I ride.

I'm going to now investigate clutch perch as my pull is stiff too. Also need chain and sprockets and sliders.

Yes. I can add some details if you're interested in DIY. If not, spend the $100 and have a reputable shop do it (Tokyo mods, etc.). Worth the effort for me.

I would be very interested if you could do that

The Protaper XPS Clutch lever will soften the pull.

Rode my buddy's 18 crf450 before and after he put an fmf system on it...huuuuge difference. Hondas seem to come leaner than any other jap bikes...have for a while. I should mention that he also put the new Athena GET cdi on it as well and then got in dyno'd. He got 5 extra horse just from doing that and shaved a few pounds with the exhaust. Later on when it was time to rebuild it he went with a JE high compression piston, got his head port and polished, switched to VP T4 and then got it dyno'd again and got about another 6-7 hp. That bike puts out around 52 stock so with all that he's around 64 ponys now. He definitely put some coin in it to achieve all that but I should also mention he has his pro license and did a handful out outdoors this year. I never rode it after the second list of upgrades but that pipe definitely made a big difference imo. That's probably one of the best things you can do, power wise, without getting 2 carried away. And if the other poster can hook you up with some mapping secrets you'd be in business. But I agree with the others too when it comes to a good suspension setup...that should always be first and foremost for everyone regardless of the bike.
