150 uphill

[KLR]

Hi, new to scooting and want to get something for my 13.5 mile commute. Almost all of this is flat and highway speed but there's one stretch over perhaps a mile with perhaps a 2.5% grade - I can't figure it out looking at topo maps. Steep, not the steepest but nevertheless, is your typical 150 up to the task of climbing such an obstacle 5 days a week, or am I just going to wear out the engine pronto, and should look for a 250?

Truthfully the more I read about it all the more I'm set on a 250 anyway but thought I'd ask you all about your experiences with pushing 150s uphill.
