Miscellaneous technical stuff around the TR1

 

Alfred (Ali) Schneider posted the following two pages of the Yamaha V-Twin development story in the forum. Below you will find the article in a slightly higher resolution. The article is from the YamahaNews from 1981, issue No. 4.

You will find all YamahaNews issues (English language only) from 1966 - 2009 here. The introduction of all 1981 models (including the TR1) is in issue No. 3 from 1981.

Many thanks to Thomas Wulff (popeye) for some information (unfortunately in Japanese) about the "small TR1", a mixture of TR1, XV920 and XV750. In Bavaria we call such a beast "Wolpertinger" ;-) Read this PDF document. Added July 2015

As well many thanks to Reinhard Utzel (old mail from 2007) for a cheap method to fix the starter. Read this PDF document in German.



 

Here is a link to the official Yamaha Part's Catalog. There you'll find the part's listings for all the XV920* models.
