The Triumph Daytona 675 is a great handling bike in standard form, unfortunately OE manufacturers have to keep all sizes of riders and passengers in mind. This requires a very progressive rear link for safety of two up riding. The RSR 675 Rear Race Link has a nearly linear rate and improves drive grip and edge grip dramatically on the rear tire.
