No no. The steering yolk allows the front wheel to turn, as normal, but as it takes on more angle it leans it over. More like a motorcycle. Speed is no real element, nor suspension compression, to this action. I understand with the balance of the car improved they behave really rather well. But as has been said. Regular checks and early servicing are best action with this unusual system. But it would not be a Bond if it were normal, would it?
My second comment is a observation humour based on the ability of this car to pull wheelies at will, or due to wind getting under the front of the car. I recall rescuing Martin Surgison (Spelling) from a crash on the A40 where his 875 was blown clean of the road, upside down into a hedge while on the way to Burford Rally. Martin is probably best remembered for his orange fur covered Isetta. Someone must have a pic of that somewhere.
Frankly, as a owner of mad and overpowered trikes I think the Bond 875 is made for you, Steve. You can put a 5 bearing 1,000cc screamer racing engine straight in, or a Simca/Pug machined oversize unit. But seeing as a standard one driven by Dabbs overtook me on the way to the Dutch Rally chasing a 750cc triple Berkeley, chasing a Porche 911, with its front wheel about 3 foot off the ground and not backing off, I am not sure you need the extra power! I did the only thing a Schmitter could do. I hid behind the nearest truck going a bit faster than I could cruise at. It was a mad day on the Autobahn.
