Iupi (with a capital i ,  not a lowercase L )
 
It's a joy expression, something one shout when having lots of fun (riding it!!! of course)
It's a spanish word, hence pronounce it  "you - pee" (Yoopie !)
It reflects my feeling when driving, and the joy of having THE bike I really want ...
It could have been "Big Grin" but in the end I prefered a spanish, single word.
 
Best regards,
