Sorry my comment wasn't clear. Basically, highways like the 400 series are just flat and boring. Most times they are congested because of traffic/commuting. You can ride just about any bike capable of 80/100 km/h without an issue. So worrying if the cbr125 is capable shouldn't be a concern. Just take your time to get up to speed. My point is, motorcycling isn't just a mode of transportation like a car. When I go out for milk and take the car, I'm back in 15 minutes. When I take the bike, I'm gone for a couple of hours or possibly even the day. If I take the bike to work, I take a different route, may leave earlier and arrive a bit late. Or I get home later. It's about taking the road less travelled. Exploring parts of the city/area you live. Finding new places. Taking in the ride. Meeting up with fellow riders or stopping for a cold or hot beverage and chatting. For new riders, IMO, I think the best experience for riding is in urban/city and country roads and to leave the flat boring highways to driving a car. You can sit in the cold or heat in comfort with your music/news and get to your destination. Not sure if I made my point clear or not. Carry on. Cheers.
