Hello From Alberta Canada

Do the Rockets suffer from the same overflow design flaws as the 1050 Speeds?
Dont know about that - but relocating the overflow allows more air flow around the Ramiar or other throttle body fitted filters. If you fit an open front bearclaw you don't want your overflow bottle in the way of the fresh air.

I've see you there . You shot my Line-x supercharged Speed Triple . Though I seem to have lost my copies of the shots you took .
 
Welcome from PEI. Do not overfill the Overflow bottle (minimum line) when engine is cold, and you shoudn't have any problems. Great choice of bike.
 
WELCOME to ya, from WA State.
Look forward to your input.
