Lambretta Gearbox Visualiser: Version 4.01

The Lambretta Gearbox Visualiser is an Excel spreadsheet that can help you to choose the exact gear ratios and sprocket combinations to suit your Lambretta’s engine characteristics and riding style. Every ratio and every combination of optional gear available is now built into the new version of the Visualiser.

I’d done quite a bit of work trying different formats and layouts as well as additional tools since the last version, but in the end I’ve decided to keep it simple. Some of the other reasons for keeping this version simple was the screen resolution that many people appear to use (small), the range of OS and Excel versions and postings on forums from people baffled with what the Visualiser was trying to tell them.

So simple (relatively) it is, and that is why the ‘custom gearbox’ feature has gone and some of the other geeky new features weren’t included. I’m still mulling over a (paid) Pro version, and these and other features will surface if I go ahead.

Some of the new features are not supported in the older .xls format, and therefore this version is in the newer .xlsx format for Excel. For those that do not have software to support this, the previous version of the Visualiser has been updated to include all new gearboxes including the Cyclone5 and options

So, major changes in the new version are:

  • Inclusion of the fantastic new range of 5 -speed boxes from Rimini Lambretta Centre – You have BOTH versions and EVERY combination of alternative ratio.
  • 4-speed boxes from DRT Denis
  • Extra granularity to show the stages in the RPM range where power increases as well as where it peaks
  • Visibility of the RPM values where the engine is not making any significant power (off the boil)
  • A button to browse through the gearboxes as an alternative to the drop-down menu.
  • Extra descriptions and keys to help you understand what this all means and what values to enter
  • Recommendations to use chain adjusters rather than stretched chains for some sprocket and crown wheel combinations

Enjoy, and please leave a comment if you like it or have feedback. You’re welcome to link to this site, and using https://avantone.wordpress.com will help me keep track of referrers.

Thanks

Tony
