Just a few words about me :
Francis post 40...(sic) moto biker (bmw s1000r) and (very) interested by motobikes performances.
I've just started to use HLT (on road for the time being - but plan to use it on circuits in France) and would like to thank Harry for this famous job !
I've bought (on Harry advice) a skypro gps as I noticed that the internal iphone GPS is not quite sensitive and has a poor frequency (1 Hz)
