Re: triumph trw speed

In your first post, you said it had an 18T sprocket (A cog is something in a windmill) Now you say it had a 21T and changing it to a 23T makes little difference??? The percentage difference will be the same in all the gears.....Are you sure your clutch isn't slipping? A 25T sprocket seems excessive to me. Ron
