Are cruisers better to start out on particularly the 1999 honda magna?

My dad (who has only ridden a 250cc honda scooter than upgradded to a 1993 CBR1000F back in the day and is now going to get but hasn't ridden a honda CBR650F) thinks I should get a 300cc beginner sports bike but the problem with that is that their too new and too expensive I would not be against getting a Hyosung gt250r or kawasaki ninja 250 but I also want to be able to do 1000 mile trips on it and my brothers kawasaki ninja 300 does about 8,000-8,500 rpm doing 70mph in 6th gear so I don't want my 250 on a long highway trip sit at an rpm thats too high for too long (on the road 10 hours a day). Cruisers I believe are easier to control so what are your thoughts on starting out on a 750cc V4 Magna or do you have a different suggestions for a beginner motorcycle. (note my budget is $3,000)

The bigger the bike the harder they fall.

Little story- Back in 1968 I rode a Honda Super 90 from San Diego, Ca. To Portland Or. And back A whooping 89cc bike on the road for 2,800 miles. Did take me four weeks to complete the journey and did spend some time seeing the wonders of the Pacific Coast but I'm still alive and breathing.

Yes bigger bikes do ride better for longer distances but you can have a great time going slower for awhile and still enjoy LIFE.

Starting on a 750 Magna is not a wise choice.
They are to heavy for an inexperienced rider to control at slow speeds.

The Honda Magna isn't a bad choice for someone looking for a cruiser, but also a bike with power. The Magna's are quick! 99 models are pretty old now so there will be problems finding replacement parts when needed. For your budget, you'd probably be better served looking for a Honda Shadow. Right now they are only making them in the 750 cc models but there are tons of them out there along with 500 and 600 cc models. Check out CL and see how many you find. Shadows are easy to ride, Honda bulletproof, excellent parts support. You are quite correct with your assessment of the smaller Ninja's. They are a fun bike for tooling around town, but they'll buzz you to death on the open road taking away any chance of enjoying the 2 wheeled experience. Yamaha/Star put out the V-Star line-up and they have a 600cc bike that is also a great "starter" cruiser. Maintenance on them is a bit of a pain in the but as compared to the Shadows, but all in all they are just as good of a bike as the Shadow.
