the original OEM is H4 50/55 W, 114U 37R

The Silverstar (Single Bulb) for Motorcycles is;
H4 ST H4 Base Style - P43t, 12Volt 55/60 amp
(Slightly higher than OEM, but I think they have been used without problems (someone can chime in if they've had problems

Sylvania also lists a Silverstar for Motorcycles;
H4 Sylvania SilverStar (for Motorcycles) 910/1500 Max. 65/72 4000K

That wattage is a bit of a high jump from the standard bulb and I didn't opt for it.

Pep Boys generally has a pretty good selection and should have one or both - That ain't a plug - I personally don't like PBoys
