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, even for road use they always were terrible.
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.
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 so that it looks similar to the original 4 bolt mag forks that the works teams used. and also to adapt to fit the AP calipers, using our cnc alloy mounting brackets.
The internal valving is removed and cartridge emulators are fitted with new springs, with brand new stanchions and seals
The std 300mm discs are retained but spacing rings are supplied to align caliper to disc, and a new spindle.
new aluminium yokes are manufactured with new stem, which gives reduced wheelbase and improved geometry with an 18 inch wheel.
All of this was developed during our 3 years racing and winning, if used with modern carbon pads produces the absolute best in performance, (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.
pricing varies depending on what parts the customer chooses to buy, for example most of the parts can be purchased elsewhere and some of you like to source your own used parts to keep costs down.
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.
