a suicide shifter I am on the fence on, I like Standard alot, but conventional is easily the safest and enables you to ride around town more.
standard has the clutch on the lever, you can put your foot down when you stop. Standard you have to just start with your hand off the bars and remove your hand while shifting which isnt too bad.
Suicide has a clutch pedal, which required you to hit neutral to stop with both feet or balance only on the right foot. If your left foot left the clutch the bike will go into gear and pop forward.
