small engine size doesnt necessarily mean safe. don't forget in a dangerous situation extra engine power may save your life: more power = more ability to maneuver and control the bike - to make it do what you want it do when you need it to. of course with more power = more temptation to fuck around, but thats all on the rider.
for safety i definately do not recommend a crotch rocket style bike. if you are a new rider, the seating position does not feel 'right'. wehn you become experienced it will be the perfect position for performance. that being said get a standard sit up style bike. one important thing - ABSOLUTELY UNDER NO CIRCUMSTANCES GET FOWARD CONTROLS. yeah they may look cool, but people dont look cool splattered on the pavement cause of the incredibly awkward position forward controls places your feet. your feet should be under you! don't get ape hangers with your hands way up in the air. buckhorns or flat TT bars are perfect for control and comfortable.
another thing: stay away from shaft drive, except for BMW models. shaft drive always causes reverse torque to be applied to the rear tire perpendicular to the movement of the bike - BAD. only BMW has developed a counterbalance to this to eliminate virtually all of the sideways torque. go for chain or belt drive only
stay away from harleys. i dont give a shit what anyone says they are fucking garbage. i have owned 3 and they all are pieces of shit. everything vibrates off, they are overpriced junk. poor mechanical design using OLD technology. resale is shit now. and that american made notion is pure shit. i had to disassemble all 3 of those bikes to fix everything that broke. MOST of the mechanical parts and EVERY electrical part were made in japan or china. if anyone asks why i owned 3 of them - i was stupid i thought they were cool and for whatever reason they USED TO have a high resale. thats what youth does - makes you make dumb choices
