Title: Re: Considering a new bike, with this transmission Post by Charon on 10/25/12 at 19:30:10 In broad terms, that's the same way current automotive automatic transmissions work. They, too, shift gears by engaging and disengaging clutches. They usually use planetary gearsets which remain engaged at all times instead of discrete gearchanges as in the video. The problem with motorcycle automatic transmissions was, and still is, controlling the timing of the shift so it cannot break drive wheel traction under, say, extreme cornering conditions. Decades ago Honda said that was why they had not put automatic transmissions on Gold Wings. Presumably the newer drive-by-wire circuits, along with traction control, lean angle sensors, and much better computational power has solved the problem. |

Title: Re: Considering a new bike, with this transmission Post by justin_o_guy2 on 10/25/12 at 20:39:28 I couldnt stay with the ad,, too much trying to convince me Id like it instead of explaining how it works.. If theyd just give me the facts, ILL decide if I want it, |

Title: Re: Considering a new bike, with this transmission Post by J C Stokes on 10/25/12 at 23:01:13 It's the way of the world. When autos first appeared in cars enthusiasts talked about "slush boxes". Today most passenger cars are autos, as are city sevice buses and many trucks and equipment. The "slush box" has given way to the Tiptronic and other autos. Mercedes ran a survey that showed that even their sports customers preferred autos. I probably won't be riding in 20 years time when most bikes will have this technology. Can't afford the $ to buy one, insure one, service one. Stuck with the S40 and few regrets. |

Title: Re: Considering a new bike, with this transmission Post by Serowbot on 10/26/12 at 00:09:18 Just learn to speedshift,... and that dip becomes a bump... ;)... |

Title: Re: Considering a new bike, with this transmission Post by J C Stokes on 10/26/12 at 00:50:58 What's speed shift? If it's without the clutch, no thanks. |

Title: Re: Considering a new bike, with this transmission Post by justin_o_guy2 on 10/26/12 at 03:10:01 I shift w/o the clutch a lot, its easy & its way quick. |

The Owner's Manual for the S40 doesn't seem to mention clutchless shifting as an acceptable practice, although it does work. The manual for my Yamaha 250 Star does mention it, says the transmission is not designed for it, and can be damaged by doing it. |

Title: Re: Considering a new bike, with this transmission Post by justin_o_guy2 on 10/26/12 at 06:08:55 Uh huhh,, I know, & thats correct, it CAN be damaged by it,,some things require a certain amount of skill, I have the required skill. |

Title: Re: Considering a new bike, with this transmission Post by 07s40scotty on 10/26/12 at 17:16:44 Yeah I too shift w/o the clutch ( mostly when I'm trying to smoke my 3 brothers on there Vulcan 900's) I dont think it harms anything, especially if you know what ur doing & are shifting at the right rpm |

Title: Re: Considering a new bike, with this transmission Post by SuperSavage on 10/26/12 at 23:39:37 If you're tired of shifting, get yourself one of those new BMW 650 scooters. They are pretty sweet. As long as you're on two wheels , you're flying. Maybe a used Burgman... |

Title: Re: Considering a new bike, with this transmission Post by Charon on 10/27/12 at 06:57:20 I have had a Honda 125 Aero and a Honda 250 Helix. I now have a Yamaha 400 Majesty and a Honda Elite 80. All have automatic transmissions. Twist-and-go sure is nice. I have not had the chance to try out one of the 650 Burgman Executives with the six-speed emulating CVT, but my wife's Outback has a CVT with a manual six-speed emulator arrangement. After playing with it for a few minutes, I put it back in automatic and let it do its job. The only time I can see it being of any real value might be on a long down-hill grade. I will point out that there is a considerable difference in the operation of a centrifugally controlled CVT and an electronically controlled CVT. |

Title: Re: Considering a new bike, with this transmission Post by 12Bravo on 10/27/12 at 07:21:18 I had a Burgman 650 for a while and loved how it would take off from a stop. Definitely a big difference between a centrifugal CVT and an electronic controlled CVT such as the Burgman 650 has. Only reason I got rid of my Burgman was to get something bigger that I can trike. The Burgman 650 will run circles around any 650 cruiser and will beat a lot of bigger cruisers off the line too. ;D |

At least one NASCAR driver has credited power steering for lengthening his driving career by many years. I don't really keep current on the rules for racing classes, but I seem to remember reading that Formula 1 forbids automatic transmissions, as does drag racing in the top classes. The reason is that the transmissions don't miss shifts, and always shift at the right time, which takes "driver skill" out of the operation. I think Formula 1 allows steering-wheel-mounted paddle shifters, which do all the work except for making the decisions about when to shift. Wouldn't take much to let the computer operate the switches. |
