This is the best way to go to upgrade your front end whilst retaining a period look.
The stock cb750 brakes are terrible, even with double discs they will not give you the power you need,
Basically the regulations for U.K. classic racing stipulate that Honda 750’s must run period forks and brakes, So that’s pre 73!!! but internals are free. These pass this eligibility criteria.
So I ended up using 70’s period AP racing calipers. but making these fit standard CB forks is not particularily easy, due to the lack of mounting points. brackets are available but they rely on the mudguard stay lug, which was never intended to take continuous heavy braking loads.
This design uses a second hand period honda fork lower, which is machined to look like the original 4 bolt mag forks that the works used. and also to adapt to the AP calipers.
Original works racers ran 4 bolt spindle clamps (which these have) and ran 37mm stanchions tapered to 35mm into the yokes. These fork run 37mm all the way.
new aluminium yokes are manufactured with new stem, which gives reduced wheelbase and improved geometry with an 18 inch wheel.
(frame strengthening should be considered if racing)
Due to the complex nature of all these modified and non standard bits and pieces, I would expect the customer to have a basic mechanical ability as the forks will need to be filled with oil and set up on the bike etc. also if you are unable to supply your front wheel, we cannot supply the spacers needed for discs and wheel, to get everything aligned correctly.
We prefer to supply these as fully built assembly, so ideally we would need your wheel and discs. or we build a wheel and discs for you, the calipers run very close to spokes and fork leg, so it is important to get everything spot on.
