in the USA and Europe, superhighway travel is common and sustained speeds over 70 mph/ 115 kph are required which the 150 cannot guarantee. The 300 single is the perfect minumum engine size.
No problem on the CBR150R, as long as you are travelling with other traffic that are pushing air out of the way for you. I have cruised comfortably fully loaded with camping gear (including large saddlebags and top case) on Hwy 400 (North of Toronto) at 75 mph sitting straight up - in those situations - with still some throttle left. Following at safe distances.
Of course - I like riding on Interstates and Express highways as much as house cats would enjoy acting out "The Hunger Games" with Ted Nugent. Are those high speeds required? It certainly would make it easier. Then again - I see lots of VW Westfalias and large motorhomes chugging along Interstates barely cresting 60 mph.
However, if you are alone on those highways - then maintaining those speeds on the CBR150R becomes more problematic - particularly if you don't have a tailwind. Or are carrying saddlebags, and a large top case. It can be a "struggle" in these situations. And what feels like a "fight for survival" if riding into a headwind, and uphill (though I also experienced this to a certain extent on the CBR250R too). Thankfully
(I can't believe I wrote that) - these highways are often so crowded - riding alone on them is a rarity. And needing
to ride on them is rarer still.
To combat issues associated with headwinds while touring with camping gear, out alone on roadways - I've recently decided to give up my saddlebags. Way too much drag on my last camping/touring adventure on the CBR150R. I will now use the top case, in conjunction with two Kriega US30 waterproof packs (mated on top of each other) on the pillion seat. Love the Kriega stuff - just snap it in - and go. My goal is to keep everything in line as best I can and reduce drag as much as possible.
Now back to our regularly scheduled programming....er.....thread topic....
