Honda RC45 NL5 – Racing History
For 1994 the Suzuka 8 Hours dropped the prototype RVF750s and required production-based superbikes. Honda homologated the RVF750R, code RC45, with a first-year run of 200 machines, and a large share of them went racing.
Parts were issued in tiers: NWA for the works team, NWS for satellite teams, and the NL5 kit a privateer could buy. That kit replaced much of the road bike. A nearly stock RC45 was not the competitive package the RC30 had been.
The earlier RVFs, raced from 1985 to 1994, were factory prototypes. The row of them at the Honda Collection Hall in Motegi in 2017 — OKI, AM/PM, Horipro and Lucky Strike — is what brought this one back onto the TYGA bench.

Building the Honda RC45 Suzuka Replica
The starting point was a non-running Japanese import, already part-way to a Suzuka replica: stock chassis, engine, tank and airbox, plus an HRC exhaust, upper fairing, race seat, wiring and dash. TYGA already held NL5 forks, a swingarm, hub and Brembo parts from a crashed endurance RC45, and later used a damaged HRC race engine for its magnesium covers and endurance generator.
HRC parts from the same year do not all interchange. Air ducts, airbox lids and the hybrid race/road loom had to be matched by version. Steve A’Lee at GT Performance fitted the radiators and tidied the wiring. Mick Laughlin supplied the top triple clamp, ECU tray and exhaust guard. Gecko supplied the airbox, brake rotors, parts books and magnesium wheels, now on Bridgestone S22 tyres.
NL5 suspension sits the bike higher, so the sidestand was lengthened, then spaced off the polished HRC exhaust. The plain aluminium silencer was replaced with a TYGA unit: a two-inch core and a Kevlar outer, drawn to the 530 mm limit of the tooling. The oil cooler came off, replaced by a custom bypass, because the race layout does not use it.
03Bodywork
Honda RC45 Carbon Fairings and HRC Bodywork
K. Thanet moulded the upper fairing, lower cowling, seat cowling, air ducts and airbox from the parts on this bike. The factory upper was thin and had to be braced before it would take a mould. The lower had been cut in half for shipping and was reshaped for a sidestand while keeping the fluid belly pan. K. Wattana’s team laminated the panels in wet carbon, with HRC-style Kevlar on the inside.
The endurance fuel tank needed about half of its shell rebuilt, including the fuel-return tube, and was finished with a genuine HRC filler cap. Painter K. Pong matched the 1994 HRC pink-red from an original NSR250 factory tank, in six coats. The number boards are satin carbon. A blue headlight cover copies the Suzuka pit identifier; the sister machine ran yellow. Lit, the cover reads nearly clear.
The RC45 has a horn, a brake light and a concealed ignition switch. No mirrors, no indicators. The paintwork was left undrilled.

Honda RC45 NL5 – Performance and Riding
More low-end torque than an RC30 or an NR750. Seamless through the gears, and it should live on a circuit.
The first road test died under load. Fuel pressure was 2.5 bar. A standard RC45 runs at 3.0 bar, and the NL5 setup wants 3.5. An NR750 regulator at 2.9 bar got it moving. A new-old-stock NL5 regulator, measured at 3.5 bar, is the one now fitted.
The endurance tank limits the steering lock. At walking pace it is snatchy. Above 12,000 rpm the power simply arrives.

TYGA Performance Parts for Honda RC45
The following TYGA Performance components are available through the European shop and relate to this RC45 project. The carbon upper cowling is the endurance-style fairing. The carbon lower cowling is a race version with a belly pan. The stock-shape race seat cowling has a closed seat and follows the outline of the road bike. The carbon front fender and gloss carbon tank air ducts are also available in the RC45 range. On this bike the paint was left undrilled: no mirrors, no indicators.
The Honda RVF750R RC45 fork cap kit is another related component, including for the NL5 forks used on this bike. The carbon and Kevlar airbox, and the clear race screen in the photographs, were made in the workshop. They are not in the Europe catalogue. A stock-shape screen is a different part, and it was not fitted here.

Also on the bike: a TYGA RVF dust cover. The full Honda RC45 range, including parts that were not used on this NL5, is in the RVF750 RC45 category.
