Safety Gear
This site is pro ATGATT and here is where you can talk about safety gear to your heart's content. It is okay to mention specific brands by name, but it is NOT okay to post commercial messages here. That is, a member can promote what he likes based on experience, but a vendor cannot post a commercial here. |

Ways to Influence the MIC-MSF via the Insurance Industry
The MIC-MSF has a monopoly in the United States and therefore it is extremely difficult to influence its practices and its curriculum. Rather than attempt a political effort to do so, some think that obtaining the assistance of the insurance industry is a way to have a loud enough voice to cause some changes to occur. Here we can discuss ways of educating that industry to gain that assistance. |

Motorcycle Accident Reports - WITH COMMENTS
Here you may post reports of motorcycle accidents from whatever source you please - Newspaper, TV, YouTube, other boards - but along with posting a link to that source you MUST add value by providing comments about what the link is about, why you posted it and what you think we might learn from it. |

Roadcraft
Despite evidence to the contrary, the MSF approach to rider training is not 'all there is' or even 'the last word'. Here we can focus our attention on one such alternative body of training knowledge - one that is rather more intelligent and well considered than MSF's curriculum. England is the genesis. |

Buying a used bike - is this a good deal?
Here is a forum in which you can ask for and discuss used bike purchase questions like: Is the price reasonable? What else should I ask for? Can the seller REALLY have just installed a NEW stator on this 28 year old bike I'm thinking of buying?
What this forum is NOT for is listing YOUR bike for sale. |

Average Deceleration Rate Calculator
Though not an excel model, this chart provides you the ability to directly determine the average deceleration rate during a quick stop when you have the speed traveled when braking began and the distance taken to bring the bike to a complete stop. |

Distance To Avoid Calculator
Ever wondered how long it would take you to change lanes at a given speed, or how much distance your motorcycle would travel (how much distance you NEED) in order to swerve to the left or right a given number of feet at a particular speed, or how aggressively you need to change directions to avoid hitting something in the road? This calculator will give you the answers. |

Effective Steering Angle Calculator
The amount of rotation you provide your handlebar is not the same as the amount of turning your bike will do. That is, your steering angle is not the angle your motorcycle changes direction by. The effective steering angle is a function of your head steering angle, your rake angle, and the lean angle of the bike. This calculator will compute the effective steering angle from those inputs. |

Speed From Stopping Distance Calculator
Used to compute how fast a vehicle is traveling at the start of a known stopping distance. It assumes that all braking is done with a constant deceleration rate (such as would generally be the case if skidding). It also allows you to include PDR (Perception-Decision-Reaction) time, if any. |

Speed Scrubbed During Skid
It is not intuitive, but skid marks do not represent speed. Instead, they represent energy transformation. That is, they represent the amount of kinetic energy that was converted to heat. This model calculates the amount of speed that is scrubbed during a skid based on the starting speed and drag factors. |
