そしてフロント周り。ショーワのSPLフォーク(レーサー用のSpecial Parts List、1994年時点で2Way(ハイ・ロースピード)減衰力調整機能つき!)のフィーリングはコーナー進入時の信頼性が素晴らしく、RSVより速く走れ、低いシート高のおかげでコーナーの進入から脱出まで400ccに乗るように膝を擦って走り抜けることができる。とても自然でとても正確に、そしてとても容易で、他人の £38,000もするバイクに乗っていることを忘れてしまう。
The RVF engine has lots more refinement. It actually makes more power than a VFR when uncorked. I think the RVF is just more corked than the VFR from the Factory. The RVF has different exhaust cams, exhaust valves (unsure what’s different), different clutch,different transmission, different alternator, different pistons, different ignition system.
All together, the RVF makes about 5hp more than the VFR with a pipe and carb jetting (even with the NC-35 carbs). It probably makes more like 7hp more if you put NC-30 carbs on the NC-35.
– VFR400 with pipe, HRC Box (the derestrictor)and good jetting, no internal engine mods. MAX Power ~65hp.
– RVF400 with pipe, HRC CDI and HRC Jet kit with no internal engine mods. MAX Power ~70hp.
– VFR400 with G-Force porting, milled heads, fresh blueprinted engine. MAX Power ~70hp.
– RVF400 with G-Force porting, milled heads, tired stock bottom-end of engine (never opened up for rings or bearings, etc.), VFR carbs (with airbox and air filter). MAX Power ~74hp.
*The alternator is quite a bit lighter. *The pistons have less skirt area (reducing friction) and are lighter. The compression ratio has been raised slightly as well. *The ports have very slight mods to them here and there (tiny refinements that don’t really show up on the flow-bench or dyno) *The exhaust cam has 5 degrees more duration *The CDI is far more advanced than the -30 *The carbs provide better response in low/mid-range
