Hey guys I am very new to bikes. Here is what is going on. I am purchasing my best friends ninja 250. I will use this while I have my permit, and plan on taking the safety course. I plan on riding for a full season and saving up for a ducati monster 696. Now here is my concern. I am worried that I might be a little tall for one, I sat on them at my local shop and I felt fine but I did feel like after an hour I would need to stretch. Im six foot two. Im also worried that this bike would get old quick. Its a two cylinder. So I was thinking that I would want something bigger after riding it for awhile. I don't like crotch rockets. Is this the case with the monster? Also I plan on having my girlfriend ride on the back of it, will this be an issue? It wont be all the time, but when she wants to go for a ride I will take her.
