I always laugh when owners always say their current bike is the best ever ...bull...its what you can afford and choose at the time.
I also laugh when someone doesnt buy a bike because of poor headlights, when 99% of biking is leisure riding in daylight.I also think you cannot possibly judge a bike by a 15 minute ride.You havent even had time to test the bike over a full range of roads and uses
Best advice is to talk to someone who has owned sprints and actually has done some meaningful riding on them. Me fer instance.I also have ridden the fazer 8 for about 2 hours , and while on its own is Ok, its not the best bike out there, many other middleweights are worth looking at .My pick is the street triple R, which I have ridden for about 500 miles just on tests( 4 seperate bikes).
You also cannot judge a stock bike by the performance of race specials!! FFS .
As for the sprint , its triumphs copy of the VFR model, but with better power and torque. Its not perfect but that engine is one of the best ever.Smooth , fast , good handling, and 12k service apart , cheap to run, or at least the same as comparable bikes. If you think sprint services are dear , try vfr and bmws...then you will know dear servicing.I would happily own another sprint .I had 2 and did 26k trouble free miles.The very first sprints had a brake issue, sorted out by triumph, so an 08 model will be fine.
