This is being cross-posted for as much feedback as I can get.

My '12 Honda CBR600RR is nearing the end of it’s life at 82,000 miles; there’s minor visible scoring in the nikasil plating in the cylinders, and that’s only going to get worse.

I can get the cylinders replated–assuming that the scoring is no worse than I think it is–for about $800 + the cost of shipping the block, but that would require being able to entirely rebuild the engine on my own. I’d probably want to also regrind the valve seats, replace the valves, piston heads, and def. piston rings if I did that. I’ve already got the cylinder head off because the valves weren’t holding pressure.

I can get a replacement engine for around $1500-2500. I can replace an engine on my own, although it’s a pain in the ass.

Or, I can get a new bike. But I’m not sure what makes and models for my riding style will have any better longevity than my CBR600RR has had.

My current short-list is a crashed '07- '12 CBR600RR (because I can easily swap necessary parts/bodywork, etc.), or a Yamaha YZF R6, Suzuki GSX R750, or Triumph Speed Triple 1050 (which is prone to electrical issues, and also needs some creative headlight adjustment to work with clip-on bars). Does anyone have experience with the YZF R6, GSX R750, or Speed Triple? Any issues to watch out for that might prevent any of them from making it to 100k miles without major mechanical work?

    Have a '24 GSX R750. Brand new so I can’t personally speak to longevity issues. That being said, Suzuki has kept this same bike since 2011 (trim changes only) which suggests it is a proven build. I think there was an upgrade to Brembo brakes a few years ago? But other than that it’s essentially the same bike 2011-2024. Needless to say its been super easy finding/selling OEM and aftermarket parts for upkeep/upgrades. As a bonus, the GSX R600 is mostly identical to the 750 for parts swaps as well.
