Product description

The big brother of the 135er is a cylinder with power reserves for problem free daily usage. Other than the small DR, the 177 definitely gets performance in higher rev ranges due to it's two auxiliary exhaust ports. This makes it a dependable companion through it's relative low compression. When the 3rd cylinder transfer port is blown (gasket), the DR can be also be driven on engines with 2 transfer ports. It also gets a respectable performance increase. With using the POLINI head and adapting the cylinder transfer port to POLINI 177 dimensions, the 177 gets more power, but won't be completely indestructible.

The OLYMPIA 177 is identical to the DR 177er, and is a very good alternative if the DR if not available.

Conclusion: a top all round cylinder with great long distance qualities.

 

Cast Iron/ 63mm Bore/ 7 Transfers/ 177.68ccm

Cast iron cylinder, 57mm stroke, 7 transfers, pistons with 2 piston rings, exhaust with additional auxilliary outlets, original DR cylinder head and gasket set included in delivery. The crankcase will not need modification in the first step, jets and ignition should be checked and optimized. Models with elestart will need modification of lower cooling fins.

 

SIP-TIPP: Adjust jets and replace spark plugs(W4AC), both an absolute must, ignition setting circa 19°, Harmonizes well with 24/24 Si, Italian racing exhausts/SIP ROAD, longer transmission and racing crankshaft are recommended. 28er carb and SIP / JL Racing exhausts are the DR's innermost desire!

 

SIP-Kunde Massimo M., Schweiz:

“Very good kit for simple tuning. Good torque. With 24/24 SI and standard gearing about 125 km/h possible.”
