    What are the differences between a 1986 VFR 700 and 750? Also, what are their comparative values?

    Thanks, Stephen

    10HP less
    10 mph top speed less

    thats about it. price is really based on condition. My 700 is near perfect condition and I paid for it. I've seen 750's that were pure junk and dirt cheap.

    On the road you'll never know the difference between the two. I put a pipe and jetkit in mine and it now makes another 5hp more than stock so it's close to what the 750 stock made.

    In short pay for the condition of the bike and not the size of the engine.

    The 700 was produced to be get around the tariffs that were place on 750cc bikes back in 1986. It is basically a smaller bore version of the 750. From what I've seen over the years, the 750 will have a higher value and is more sought after.

    I was just wondering about this very subject. I posted in the chat box about the 700 and this link was posted in response....

    http://pages.cs.wisc.edu/~john/vfr/specs/86-87-vfr700f.html

    It says 76hp and 42ft-lbs torque for the 700. I don't believe that # unless its rear wheel on a not so great running example. Check out the page for the 750....

    http://pages.cs.wisc.edu/~john/vfr/specs/86-vfr750f.html

    They say 105hp on the 86 750, which is inline with other sources I could find. No way there is a 30hp difference in the 700 vs 750 so I think that 76hp # is wrong. There is only a 5hp difference in the 1984 700 vs 750. 577nitroexpress's 10hp or less between the two sounds right to me.

    76hp would mean the 1986 VFR700 has 5hp less than the 84-85 VF700. No way.

    I was interested in this because there is a good looking example of the 86 700 for sale on ebay right now.

    http://www.ebay.com/itm/231376759502 This auction should answer the current value question on the 700 for us.

    Try this link. 94 HP at the crank. That sounds about right.

    About 2 years ago, I sold a 1986 VFR750F in excellent condition with 24K miles for $4K. The 700s won't typically pull the same amount of money. Since these bikes are harder to find by the day, especially in great shape, I'd wouldn't think twice before buying a 700.

    Get the facts correct.
    The bores are exactly the same. The 700 has a shorter stroke.

    No, bore is the same, stroke on the 700 is shorter and the rods are longer to get the 700cc. Besides that they are the same bike.

    VFR700 = > 92 HP
    VFR750 = > 102 HP

    To try and keep performance the same, Honda lowered the gearing on the 700 to help acceleration and roll on. The 750's would achieve higher top speeds, but not by much. Truthfully I doubt a 750 can pull redline in 6th. Most bikes need to geared lower from the factory. I have the 17" F2 wheel on my 700 and with the CBR 43 tooth rear sprocket could not pull red line in 6th. This is wasted HP. I re-geared to the stock 45 tooth in the rear and can, clean, pull 11.300rpm in 6th. For me, however, I'm also fighting against high density altitude condition living in CO. AN engine looses 2% HP per thousand foot of pressure altitude. So on a standard day 67 degrees, 29.92 BMP, my 92 HP engine is really making 80.96 hp at the crank and probably 68 HP at the rear wheel. 68 HP is good for about 130MPH max. A 750 would make 78 at the rear wheel and maybe could do 138 to 140. On a hot day during the summer pressure altitude is even higher closer to 8000' which yields even less power and fatter mixtures equalling even less power, probably closer to 62 HP at the rear wheel (700).

    I was about to say I would eat my hat if my stock 750 produced 102hp until I read your post further.

    I think you guys forgot the biggest difference between the two and what would be the biggest issue for the owner.

    The 750 has VFR750 on the bottom of it's side fairing and the VFR700 just has VFR.

    I have had to point out this fact to feebay sellers trying to sell 700 fairings as 750.

    Yup, probably corrected for temp and altitude. But 89.3 at the rear is pretty dang good for 2nd gen. My 4th gen managed 88 stock.
