I've got a 150r for sale, it's one of my wife's bikes. Every time someone wants to see it, I'm out of town. $2000 firm to a RDP member, just serviced at champion honda in newport beach.
are you looking for the bigwheel or smallwheel? My bike for sale is the smallwheel with the bigwheel swingarm currently on it which makes the seat height 33-1/4". I have all stock parts
Stock The 150R seat height (14" rear wheel) is 32.8" the 150R expert with the 16' rear wheel however is 34.1".
we also have a 150r bigwheel I like to play on. You could buy a bigwheel rim/tire set for $500 on ebay and set-up my bike for both sizes still within your budget
