get you kicking leg ready if you're coming off a 2 stroke to a big 4. you can hand start a 2 stroke 125... big four stroke requires some big kicking. also remember you might not hit a compression stroke every kick like on a 2 stroke. can be frustrating, but the endless torque and fewer gear changes are worth it. I have an 08 with a big bore kit on it and my son has a stock 08 450. My six year old grandson can start both of these bikes by himself. It is fun to watch and a great way to win bets with friends for cold drinks. My bike is by far the easiest starting bike I have ever owned. Last week I did a couple of dead engine practice starts with Dave Pearson and I could beat him out of the hole each time. Even he was suprised at how easy my bike started.
