After 1983, Honda Racing Company, didn't give up motorcycle turbocharger technology completely along with NR racer.
HRC started developing another turbocharged motorcycle, based on VT250F, a 250cc 90 degree V-twin, liquid cooled, DOHC engine, mainly sold as a domestic model, few were exported several countries.
You may know it as this:
In the beginning, this concept was designed to attempt WGP with 4 stroke 250cc which used to compete along with the 2 stroke 500cc race bike.
The VT250RT engine recorded 150ps (147.95 hp)/11500rpm with no melt and/or blow. weighing in at only 170kg, apporox 375lb it had a serious power to weight ratio advantage.
With this is a successful result, HRC engine development engineers made a running prototype.
Unfortunately, they realized in the real world, the VT250RT was had too peaky to control. Turbocharger activated around 7500rpm and accelerated at approximately double the speed of an NS500, Honda's 2 stroke WGP racer.
HRC gave up their challenge at this point.
They detuned its power into 90ps (88.77 hp)/11500rpm and tried to put this model into the 1985 catalog.
The IHI made turbocharger was placed beneath the front cylinder block, and considerably smaller than the CX series turbos.
Like as V4 Interceptor, the VT250FTC was given an Hydraulic clutch.
In 1984, Honda approached the Japanese Ministry of Transport, much like the United States Department of Transportation (U.S.DOT), to approve this VT250FTC for domestic sales.
The government denied Honda the permit to sell VT250FTC in a domestic market model.
How about export?
Unfortunately, during this time, some countries were claiming of Japanese motorcycle companies, "They are selling dangerous motorcycles that their government refused to sell at their domestic market."
The 1985 Honda VT250FTC was cancelled, and this model was hidden and stored years at Honda R&D storage.
Honda's foray into turbocharged motorcycles had officially ended.
