I know that feeling. You'd not believe though how much lighter my 1600 tbird feels compared with the two LTs I ran a while back. Partly weight reduction and maybe shorter wheelbase.....I used to have a mild feeling of impending doom with the LTs when pulling up at junctions.
These days I also run an old Tiger 955i and it feels a fraction of the weight.
About to do a 500 mile run on Friday and haven't decided which to take...they'll both do it well, just in different ways.
