Progrip 761
It's a sport touring gel grip, and listed as a scooter grip now.
They are a larger diameter in the center and taper down towards the edges.
They aren't rock hard or soft and squishy either, it's a happy medium.
Here's an old pic(hadn't put the throttle grip on yet). They aren't stock bars pictured but the grips will fit stock bars.
They have made a big difference in hand comfort for me. At around $25 they are cheap enough to try.
Also, the larger and heavier the bar end, the less vibration you will have.
The more vibration you have the more your hands will feel numb.
Grips are a personal preference, but I doubt the aluminum grips will help you at all. I've ridden bikes with them and you can feel alot more vibration with them. As well as being solid and having no cushion or give at all.
Here's a link to them on their website too. I'm also not the only one using these on a busa, as BigE recommended them to me. Money well spent!
