I have just read the article in full in performance bike, I put a link on here last week. on the 24 hour track session the 675 snapped a valve off its stem, the bike had a hard life but a short one having racked up 9000 miles befor the test, the cause? Triumph say at some point the valve had come into contact wth the piston! The dealer who did some work on the valves says it was not them, the magazine say the bike has not been in bits from when it was assembled on the line in production until the dealer did the work, did the dealer screw up they say no, I hope no as there my local dealer Triumph say? I say if I had a 675 around the 10,000mile point I would be a little worried, no problem as the bikes will all still be under warranty, but a bit down the line if your bike is not used for high milages and you get to 10,000 miles in three years where do you stand re repairs. The Engine alsohad evidence of burning exessive amounts of oil, come on Triumph tell us if there's a problem, I do want a new triumph in 08 so put my mind at rest. :???:

I bought my 06 675 in mid 06. I have 10,500+ miles on it and I ride the hell out of it. I do not baby it nor do I intend to, ever. Mine does not burn oil. I have topped the bike out for miles at a time without incident as well as fast twisty riding in the 40-100 mph range where this bike shines. I think I have given my bike a pretty god bit of "stress testing" witch it has taken in strided and begged for more. I say break it in right, then beat the hell out of it, if it last through the first few thousand miles you should be in the clear. I think this bike has the same problems any bike has there just arent as many of them so you here more about the problems. saying any of this happened because it was a triumph is bs and they know it.

Glad to hear it honestly, the pretext for this test was that the bike had done over 9000miles and they loved it, the said however they did not know how reliable it would be long term so a 24 hour track race was decided on, it broke pretty quick, the thing was they said the valve could have been damagd as described above. My problem is that the dealer is the one who does my servicing! and have only been a Triumph dealer for about 5 months. I recon they screwed up.

I would be extremely surprised if this was a "known" problem that Triumph arent telling us about. I would also be inclined to give the dealer the benefit of the doubt. Given enough stress any mechanical device will break.

Whats to say that particular valve wasn't faulty from the point it was manufactured? Its easy to speculate forever.

detjan, over on the Sprint forum has a 04 ST that has been using oil for a while with no evidence of where it was going. A very odd problem indeed. The dealer pulled the motor down at the beginning of December and discovered a problem with the valves that has been with the bike since new. Since the assembly is unique to each bike, Triumph asked for the top assembly back and are replacing it all under warranty.

This bike and now the 675 with a broken valve are the only major terminal "faults" I've heard of, having owned four Hinckley Triumphs since 2000.

Sleep easy and keep enjoying ride!

Brett. :-D

to me it sounds like when the dealer adjusted the valve clearances either the engine was not at TDC or too large a tappet was put in, the engine was turned over by hand at which point the valve touched the piston to stress it, at which point they realised their mistake and adjusted again, but it could b plenty of other things, and if there was a serious fault, triumph definately would recall them, they would rather replace a single valve/valves than replace all 4 valves, piston, liner, cylinder head and all the rest, i wouldnt worry bout it, if it was the dealer's fault and they know it was, they certainly aint gonna let it happen again

my tt dropped a valve (@28000 almost abussive miles). Could have been one too many trips to the rev limiter, that broke your valve.

but dang what a mess those valves make of a perfectly good head.

the tt is alive and kicking again, after abunch of parts and money
