Close ratio gears for CB250/350 and CB500 on way
« on: October 10, 2024, 10:51:35 AM »
Just an FYI! I’ll put up a separate ad on the for sale section with actual pricing and whatnot, I just wanted to post here as at least myself, I don’t look at the for sale section that often .
 I have been working with Nova Racing in the UK for the past year to develope some close ratio gears for Honda CB250/350 K twin and the CB500-4. I have a batch of close ratio gears for both 1st and 5th gear available for both type engines.

1st gear is a 37t, down from 40t (uses same mating so, 17/37 now) and are drop in on all engines.

 For 5th gear, it is the same as previous Nova delivered, but no longer offered, 29t (29t/27t). This one is square dog design, so drop in for the 250/350 K. On the CB500, you must swap on the 2nd/3rd gear cluster and 4th square dog from the CB350K, as the CB500 is round dog...this is the only change and good used gears are availble for next to nothing on Ebay etc.

These are not a stocking item at Nova and not available for purchase direct and likely a one time order from myself....only 10 gears of each type available

Turboguzzi may be correct but I'm interested for my 500 land speed racer.  In fact, I have a ebay OEM CB350k 2nd/3rd gear cluster arriving today.

The 500 gears are actually selling better than the Twin gears.....In the nordic racing series, Norway, Sweden, Finland and Denmark, probably 40% of the bikes are CB500. Two of the top three are CB500, the other being a Drixl 450 big bore. But that said, it's not a money maker, I'll be lucky to break even, but it will get my Dresda CB500 hopefully firmly planted in the top group if I'm lucky.

I'd be honored to have one out on the salt. As a 200mph Club member, that place has a special place in my heart. As you know THE MOST important gear change to have a close ratio is the top gear. Send me a mail or msg and I'll get you sorted.
