The Famous Blackbone 2 Speed System for the HPI BAJA!
Order the correct gears (2 sets ideally 2 ratios apart, ie 19/55 and 21/53)
The kit contains:
- HD steel clutch bell (15mm shaft diameter) (NEW V2 DESIGN)
- HD 2 speed custom layshaft with one way bearing system
- 2 speed Alloy Spur gear carrier
- Get the best of both worlds for your Baja, Groud breaking launch and hit second gear for that top end speed you are looking for. Don't choose between torque or speed. Get both with this BBRC two speed.
-
Gears are available via separate listing, this is just for the 2 speed system.
IMPORTANT GEARING ADVICE:
- Don’t set the difference between first and second too great or you’ll notice smaller engines will struggle to pull second gear. a Maximum of 4 pinion teeth for the jump, eg 18/56 and 24/50 will be rubbish and no point buying this system for bad performance
- For most tuned zenoah style engines, start with 18,19 or 20 for 1st gear and go for 20, 21 or 22 for second gear, youll get the potential from the engine and the transmission this way.
- My advice on 24/50 is that only really for 40s or twins. 23/51 is plenty for second gear on even a very powerful 34cc.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

The snap to put them together.

This came in handy in the foyer. I didn’t want to see the door from my couch. I must be weak found it hard to snap them together. I kept 2 my daughter took the other 2.

I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.
