that's not a bs quote, its close to what you're looking at. On the highway where even a Ninja 250 is adequate a DRZ will have a harder time, not that it can't be done...but for what you want to do I'd go the 500 or 650 route. Also don't kid yourself into thinking after 10-15 rides or about 1000 km you've gotten bored or 'know' what you're doing.
In my neck of the woods and most of the the 'real' riders here 1000km is just an average nice weekend's worth of riding....
ps...
Miss-Loo hwy is the most boring ****ing route and will do nothing to improve your riding skills. Honestly, if you can take the extra time go up Trafalgar, hit Side Rd. 15, keep going past Guelph Line, left at the very end of the road, right where the road you're on turns to gravel but the one you're turning on to is paved. Then blast it down all the way down to hwy 6 and turn right. Turn left on Victoria or any major road and it takes you straight into Loo. Its usually quiet on these roads, enforcement is low and when it opens up you can really rip it. Just don't on hwy 6.
You will actually improve as a rider, have so much more fun with your bike and have a fun time getting to school (I'm assuming) whereas on the highway you're just sitting there thinking there's not enough power and you've gotten 'bored'. My cousin did the hwy route all summer on the 403 after about 10,000 km thought he was pretty good. Then he'd come on a proper ride with me, not a 'commute' and I'd hate it because the whole time I'd be looking back making sure he's ok and its even worse when the person is family and got into riding because of you! Any time it got slightly challenging he'd just lose his **** and crash...at least 3 ****ing times that I can clearly remember with me on the most intermediate corners when I wasn't even fast and once in the rain.
One time he ****ing crashed literally 5 min after leaving the dealer turning right at Woodbine/Derry. I leaned nicely and went through the corner whereas he got scared or something when he saw that little extra center median with the yield sign some right handers have. I look back see him laid out and thought wtf?? How'd he **** up there?? Turned around checked out the bike then limped our way back to the dealer to get the dumbass a new shift lever. Needless to say I pretty much wouldn't let him ride with me after that
Point is going straight putting on km's just does not add to your skill set or put these type of spontaneous situations in front of you in which you have to react quickly and maybe differently to what you're accustomed to. After 1000 km you haven't even scratched the surface so be very aware that things happen very quickly on two wheels and **** ups are very costly, and I'm not just speaking monetarily.
