Is there much to choose between SKF, NTN etc when selecting new bearings for the primary shaft on a 400/4. I'm not trying to get the cheapest just decent bearings. I notice that some NTN bearings are made in Taiwan rather than Japan - this maybe irrelevant......
The bearing grade makes a fair difference to the price of a bearing. eg SKF 6205 c3 is £3 and a SKF 6205 C5 is £12. Anyone know what grades Honda use in the engines. Snap ring ones are getting a little costly now. https://www.ebay.co.uk/itm/143632266103?hash=item2171267377:g:jycAAOSwA7de1PkW&amdata=enc%3AAQAIAAAA4A3VM1rQb6B%2FpmZZd28jgy46pfHHPlAVbMfUKld1Fp7Gq81asoHuLo%2FWE3BEBPAQ5MP2Z%2FjI%2FCLbchskWQa0Zbe3AQQdC9gkXFqIkQ97whF6CvVWuCGSubRsc%2FCieEAjQHpjce9nCTLlqjCHKj%2BEYCfW1RZZf2nfyxfsGc6lQEEw9CJs8WIWvTWh3vLce1pLMiOhI4F2byoaWmHqg2Y4G7xebvFhyHq%2FMugq8Z7heQRbInZie%2BCDjjJy8%2Ftfaeq7%2Fo2wwqIV6C6WIXzvLna9JNsINV2tmf2ThGwT3MLhwUbZ%7Ctkp%3ABk9SR_qwj865Yg

I can't remember ordering anything other than C3 for any of the engines.
More modern bike with higher revving engines have more clearance. I have a bearing data book somewhere for motorcycles up to the year 2005 but, have not looked at it in years as they keep changing with higher revving engines on the gear box. All SOHC engines are happy with C3 Chris
