The modern Honda CR80/85 was produced between 1996 and 2007. At BBR Motorsports we build products for 4-stroke off-road motorcycles, so it may be surprising to see products for the 2-stroke CR80/85. The simple fact is that we have used the CR80/85 chassis components on a bunch of 4-stroke conversion bikes. That means that CR80/85R owners benefit from some available items (like adult rate suspension springs).
