919 motor life expectancy?

What is the expected number of miles you get out of a 919 motor, assuming good maintenance and moderately aggressive riding style? And then do you rebuild or just move along, assuming you like working on bikes?

Many, many, many miles. The rest of the bike will be unservicable before a properly maintained motor craps out.

Thanks, I missed that. I searched for "rebuild"! Now I know why that search returned 0 results!

Been off WT for the most part for the last 18 months. Still amazed by the 919 community.

Nobody knows. No one has ever worn a 919 engine out.

I used to take it real easy on my equipment. And I don't beat on stuff now days, but everything I have has a groove worn into where the throttle meets pin. They make new bikes every day.

Yeah, I don't think we're going to be finding out any time soon. The parent bike for our engine is the 1992-1999 CBR900RR; there is a documented example of a pretty badly beat up 1992 cranking out 325,000 miles and despite looking like hell it was still going when last heard from (per a 90s article in Sport Rider). None of the (patched) plastics matched any more due to the multitude of drops over the years, it'd gone through some stators and it'd had a minor frame crack rewelded - but it was still going on the original engine with no evident sign of performance reduction or engine wear.

You are going to get bored with the 919 long before it gets close to wearing out the engine. Long, long, long before. So don't count on it wearing out so you can use that as an excuse to get another bike - because it's basically not going to happen. After all, it's a Honda inline four.

In thirty years, most of our 919s will probably still be around and most of the contemporary competition will have long since succumbed to engine failure.

I have my Great-Grandfather's axe. It's on it's third head and 8th handle, but, it's still his axe.

Unless you break the actaul case, most everything is replaceable. The engine will most likely live longer than the bike frame/subframe/electronics/wiring. Then again, all these parts are replaceable!

"In thirty years, most of our 919s will probably still be around and most of the contemporary competition will have long since succumbed to engine failure."

I was under the impression that *most* modern import bikes (specifically the Japanese ones) were tough and you could expect a long life, of over 100k miles. Is this not true?

I'm asking because I just lectured a good friend about his mid 90's honda cbr600. He's worried about the motor and wussin out on wanting to take her on the track. And I told him that as long as he changes his fluids and keeps his carbs in reasonable adjustment he probably couldn't damage it if he tried!

Not necessarily true for sportbikes and sportbike derivatives in the 600-1000cc class. Because of the extreme hyper-competitive spec-sheet-driven nature of that market segment, makers will often go to extremes to get a little more power or shave a few more ounces off. This results in reduced longevity. For example, a Yamaha R1 is lucky to get to 100K without having at least one rebuild; a GSXR-600 might not even see 80K.

The only maker that seems to refuse to sacrifice longevity for spec sheets is Honda. Most make-specific forums consider 50K to be "a lot of miles" on a bike. Most Honda forums don't consider Hondas to be 'broken in' until 50K. Consider that.

As for the CBR, maintain it per Honda's recommendations and it is exceedingly unlikely to ever have a problem. 200,000 mile CBR600F4i, anyone?

Fair point under most circumstances. I'm pretty attached to my 919, though. I've been driving my F-150 for about 12 years--similarly, 919 probably ain't going anywhere. Love that bad girl!

Actually, I've never done an engine rebuild/project bike so I was trying to determine if I should buy a second bike as a project or a newer second bike if the 919 would eventually need work.

Looks like I'll be scouring Craigslist for a project bike...

200k miles?! holy shit. I wish i had that much time/ money to travel the us. NOT IN THE SNOW. lol. And not on a hunched over cbr. I like the cbrs, but i can not imagine riding THAT much on one. Id want something more comfortable, even more so than my 919.

Cool video, good proof of Honda building some pretty bullet proof stuff. Wonder what he's spent on repairs if any major?

IIRC, from some posts he's made, no repairs whatsoever. Maintenance like chains, tires, brake pads, sprockets, yes - but zero in mechanical repairs.


Edit: Whoops, I was wrong. He's had to pull the trans out at 114K and had the CCT fail a few times. I was thinking of a much older post he'd made. Anyway, read his report for yourselves, and check out the engine internals pictures:

The bike will outlast you in all likelyhood.

I had 77,000 plus on mine, likely over 80000 had I not "healed" the speedo. At any rate thier is a tear down thread on here somewhere. The internals looked great. And I was not particularly nice to the bike. The rev limiter got a workout nearlly once/day. Sometimes more. And it had gone to several track days and dragon rides. And adventure rides.

Hey I know that guy

He's one of the moderators on another forum (3geez.com - One Site. Three Generations of Classic Accords - Powered by vBulletin)

You can see his old Accord in the video
