[QUOTE="Monkeypants, post: 108995, member: 2708"] My OZ Rapide arrived with a very quiet and restrictive Toga fitted. Toga makes or made at least two types of silencer for a Vincent twin, open and fully baffled. Top speed was around 80 mph. I thought, OK this is a mighty Vincent. Not impressed. After drilling out the baffle with a 1" steel drill bit with welded extension, the bike came alive. I saw 115 on the speedo and that was in mph. On the local dyno hill ( about 15-20% grade ) the bike had previously dropped down to 60 mph at top of hill with a 70 mph start at bottom, top gear used. After the drilling it managed to pick up speed on the hill, going over the top at 72 mph! A few years later I purchased one of the Spares Co. spiral baffle silencers. I have not found it to provide the near magical power transformation some true believers claim. If replacing a stuffed up silencer, then perhaps it would seem magical. It gives the same performance as the crudely drilled out Toga, a 70 mph start gives 72 mph top of hill using top gear. Glen [/QUOTE]
