ok well this is something you may want to look into, the triumph daytona has a soft head, needs the shims checking a lot and after 20.000 generally need a new head, very very exspensive, it would be worth checking for that problem on a triumph forum for the sprint, that being said, it doesn't seem to be for all but is a gamble i definately would rather not take. the vfr?? honda = bullet proof engine, looked after can do up to 200,000 i've herd (read) about. Im totally bias tho as I ride a honda, the old man has a triumph but it's currently at mine waiting to be fixed while he rides his more reliable ummmm honda.
