I asked Tom (son-i-law) to assist in doing oil changes today on four bikes, Thruxton R, T-120, Bobber, and Speed Triple RS. The hardest of the group is the Bobber due to the low ground clearance. The twins all use the same filter and I bought them from Amazon (https://www.amazon.com/dp/B08TRPW8Q4?psc=1&ref=ppx_yo2ov_dt_b_product_details) and they were Triumph genuine filters that came with new crush washers for the drain plug. The RS uses a different filter (smaller) and it didn't come with a new crush washer because it was an off-brand (https://www.amazon.com/dp/B07FZJ2CCW?psc=1&ref=ppx_yo2ov_dt_b_product_details). So the annual ordeal is done on the bikes I'll be riding this summer and fall.
